You don't need to run stovpchiki on your computer. Know the sound on your computer or laptop - what to do? Incorrect sound adjustment

The main components of the computer's acoustic system are the sound card and the output audio device - speakers (speakers) or headphones. Sound cards of modern computers are sold in two main categories:

1. integrated into the computer's motherboard (on board);
2. Around (discrete) sound cards that are installed in the middle of the computer system unit.

There are also cheaper or even more expensive (for professional music) external sound cards with a USB connector.

Widely expanding the first option transfers the unsoldering of sound microcircuits on the motherboard. The more precious the remains, the better the microcircuit is located in it. However, in this case, the vibrancy of the sound in on board maps cannot be called high, although ordinary players are completely satisfied with it. Injection of the transcode near other elements of the system unit must be carried out until the audio signal in such cards is detected. In addition, if the processor is very busy, the sound will stutter.

The real audio characteristics are determined by discrete sound cards. The audio signal in them is processed by a specialized audio processor. The delivery package of such a board includes a special security program that implements various acoustic effects. It does mean, however, that the potentially high sound brilliance can be neutralized by ordinary speakers and headphones. It is recommended, strictly speaking, to use speakers with a wooden body.

Cause the sound to fade

Sometime after the computer is turned on or during an hour of operation, sound may occur on the computer. Why is there no sound on the computer? The cause of the problem or confusion may be problems with your software or hardware storage:

• bad contact and output from the speakers or headphones;
• incorrect settings of audio devices;
• driver upgrade;
• malfunction of the sound or motherboard (for the on board option) board;
• inconsistency with other programs and drivers;
• incorrect BIOS settings;
• action of viruses.

The simplest ways to update

If the sound is only heard, then restart the computer. It appears that the problems with sound are a legacy of a malfunction. If the problem persists, reconfigure what is turned down and not turned to the extreme position to remove the speaker columns. Then visually check the reliability of connecting the speaker plug (or headphones) to the power (green) socket of the computer. Poor contact with the socket can also cause the sound to become hoarse. The effectiveness of the speakers themselves can be verified by connections to another sound device - a player, a smartphone, another computer.

All line versions of the operating system that are tested are Windows 7/8/10, as in the older Windows XP, and there is a universal tool – “System Update”. Vіn allows you to turn the computer to the correct position. If the sound is normal, for example, every day or day, you can “scroll the year of that” and turn to that state. Hovering below the screenshot of the windows that are subsequently opened, the rotation algorithm is explained (“Control Panel” -> “System” -> “System Protection” -> “Update” -> selecting an update point -> “Next”). After the computer is automatically restarted, the sound may be restored.

Adjusting audio parameters

Unknown computer users may have unknowingly turned off the sound from the control panel (crossing the speaker or scrolling down). If this is the case, then you need to update it, as shown in the screenshot (to see this, click on the speaker icon).

Then go to “Start” -> “Control Panel” -> “Administration” -> “Services” and scroll down so that the Windows Audio service is automatically launched; Otherwise, restart it.

To check the audio settings, go to “Start” -> “Control Panel” -> “Sound” and go to the green check mark next to the sound device. This means that the stoppers work. Otherwise, click on the “Powerfulness” button,

Then open the bottom list in a new window, select the term “Victory this device” and click OK.

Reinstalling drivers

If the sound card is useful, you can go to Device Manager: “Start” -> “Control Panel” -> “Device Manager”. After opening the “Sound, video and game devices” list, the presence of the model (Realtek High Definition Audio) and the presence of a series of alarming yellow sign means that everything is ok. If you press the right mouse button on this row, then “Power”, then a notification “The device is working normally” will appear in a new window.

Otherwise, you will need to update or reinstall the driver. This very need arises after the installation of a new, often absurd device and program. To update, press the right mouse button on the Realtek High Definition Audio row and press “Update drivers” in the list that drops down.

The new version will introduce two ways to find updated drivers with explanations.

In some cases, the effect is only achieved after removing the driver (see front screenshot) and installing it again from scratch. The Windows 7 operating system must automatically install the current driver (Plug and Play) when re-installed. If this is not the case, the required driver can be taken from the disk, which is included with the purchase of a discrete sound card or motherboard. At the very least, the driver can be found and downloaded on the Internet on the website of the card or payment manufacturer.

Malfunctions of the sound and motherboard

These malfunctions are reported to the warehouse and detected on a specially equipped service unit. However, if you find the same computer in your office or office (for example, in your room), you can replace the suspected board with a known correct one. After checking this way, the problem may be resolved by purchasing a new board.

Setting up the BIOS

It is possible that an uninformed user has unwittingly selected the integrated sound card in the BIOS settings. To enable it, you need to restart your computer, go into settings (by pressing the Del key until the system is started), find the Onboard Devices Configuration section and replace Disabled with Enabled. At the same time, please note that if you use a discrete sound card, this option may be disabled.

The absence of sound may result from insufficient anti-virus protection. Sometimes you need to carefully scan your entire computer, perhaps using other antivirus programs. Once a virus has been detected, the drivers will need to be reinstalled, as described above.

Visnovok

There are consistent recommendations to restore normal sound on your computer. Similar reasons can be noted in other articles of the sound question “What is the sound of a computer.”

The situation when the sound on the computer disappears is often dealt with. As a rule, without warning, people have turned off the computer and that’s it, but it’s quiet and there’s no sound.

It is necessary to understand that nothing is just expected, it is worth the sound in the computer.

Forgive reasons

Most of the time, the software crashed, for example, the drivers crashed, the sound settings were set incorrectly, or there was a hardware problem - the sound card or speakers went wrong.

There are also simple situations that can make an experienced PC user laugh.

For example, they unplugged the speakers or forgot to press the power button.

And there are situations when the sound changes to a minimum, or headphones are inserted into the sound jack. In this case, you just need to plug in the plug from the socket on the speakers or sound card.

For these reasons, it is necessary to start looking for a problem, which is why it is necessary to go from simple to complex.

Before finding a problem, try rebooting the computer again, there will be problems when everything returns to normal and the sound appears.

If you have identified a reason for the absence of sound, click on the sound icon in the tray at the bottom right. In principle, you can earn money right away.

If the icon has a red crossed circle, as shown above, then the sound of deactivations must be turned on and the required volume must be set.

Try connecting the speakers to another device. This can be either an iPhone or a mobile phone, so that the plug is suitable, but, as a rule, at the same time, there will be no problems.

Since the speakers interact normally with other devices, we move on to the next stage of finding the problem - the software stage.

Accessing the Device Manager in Windows 7 is difficult. You can do this through the Internet panel or by pressing the right mouse button on the “Computer” icon on the desktop and moving to the “Power” section.

There you will find the Device Manager menu and go to this section.

All devices are liable to display without power signs, especially in the “Sound, video and game devices” row.

If the power sign is displayed there or this section is not working, you will have to install the driver.

You can use the additional disk that comes with your computer, which will save drivers for all PC devices.

If there is no disk, then using the additional program CPU-Z, AIDA64 or HWiNFO3264, which is not important to know on the Internet, check the model of your system board or sound card.

If the sound card is integrated, then the type and brand of the system board is determined.

If it is not integrated, then it is recognized as the same or only for the sound card.

You can do it the simplest way, download from the site http://drp.su and burn the remaining driver collection to a DVD.

Rub the disc under your hand. After launching the software package, the entire computer will be scanned automatically.

Next, you will be asked to install the driver that was not found for devices or update older versions. After rebooting the computer, the sound may appear.

System upgrade

No system updates benefit anyone.

The sound of the computer may occur after installing programs or drivers that begin to conflict with existing ones.

Guess what you installed the next few days. Try Vidality software.

If it didn’t help, go to the secondary section through the backup panel and turn the system back through the selected update point.

The data will not be stored at any time, except from the desktop, for safety reasons, but its traces will still be saved to a non-system drive (D, E, etc.).

You need to select a refresh point where you know for sure that the sound on the computer is real.

However, situations may arise if the update point is not created or this function has been enabled to the C drive.

To solve our problem, you can quickly solve it using the sfc.exe utility.

Log in to the system with administrator rights. Click start - close, enter cmd.exe in the row and click OK, the Windows command row will start.

Wired devices

There were situations when, when connecting other devices that produce sound or edit it, sound drivers were installed on the computer.

After turning on this device, if it is no longer needed, the sound disappears, and the remaining parts of the device will appear on their own. Is it already turned on? How to get out of this situation.

We need to switch to work with the installed sound card.

Go to the panel - sound.

We are sorry that the device is not connected. When you try to turn it on, nothing appears.

Now press on the empty area with the right mouse, it will appear like this.

Show disabled devices.

Just like that, “Speakers/headphones” appeared.

They are deprived of their strength.

The sound of the computer may appear.

To check this, go to the Adjustment section.

And then “Re-verify.”

The sound is clear and without distortion.

The situation here is slightly different. If the system turns on the speakers, the culprits will appear in the already familiar “Sounds” window.

If it stinks, activate them and go to the “Power” section.

Below, look at the row “Storage of outbuildings”. There may be “on”.

Return respect to the “controller” row. The device is at fault because there is nothing there, which means the driver is missing. How to install it, we wrote more.

In the “Additional” section, you can check the sound level and brightness by pressing the “Check” button.

Look for problems with system services

Windows Audio is responsible for the sound. If it turns off for whatever reason, there will be no sound on the computer.

To assign local services to services.msc, enter the “Start” menu in the search bar, as shown below.

Go to the Windows Services panel and find the Windows Audio row there.

The service station may be “Pratsuє”. If it is turned on or set “manually”, click on the mouse to go into settings and set the startup type to “Automatic”.

The sound card can also become damaged. If the described methods did not work and there is still no sound, try replacing the installed sound card with another one.

Ask your friends and acquaintances for it. Or take it from another computer, if you are in it.

Alas, you may have to install the drivers again, but you already know how to do it.

As a rule, modern PCs have a sound card already integrated into the system board.

However, many computers in the world are not satisfied with these characteristics and require more advanced devices that can be inserted into a PC slot or connected via a USB port.

If you need to understand that if there is no sound and to get the most out of your device, you will have to go into the BIOS and turn on the power supply for the integrated sound card.

Otherwise, after connecting the speakers to a new, current device, there will be no sound.

The sound manager can be transmitted via the sound card connector to other devices.

For example, behind the green rose there are indications for connecting headphones and speakers.

Chervony – for the microphone.

Everything is registered in the registry. However, as a result of any manipulations with the remaining adjustments, changes may occur.

To turn everything around, you need to go through the control panel to the “Realtek HD Manager” and re-recognize the roses there.

It’s a pity that the sound manager is not available on all computers; it depends on the type of connected speakers and sound card.

In this situation, you will have to go to the registry and manually edit everything and update the registry from backup.

The folder where you can find the exact working registry files is here.

The config folder has settings for the sam, default, software, security and system files.

Backup copies of these files, which are created every 10 days, are available in the RegBack folder.

If most of the over-the-top methods do not help restore the sound on your computer, you can try replacing the existing registry files from a backup.

You won't be able to work with the current Windows OS. You will need to become familiar with another OS, such as a Live CD, which operates only through the computer's RAM.

Once you’re done, go to the config section and add the sam, default, software, security and system extension “old” to the files.

Now, from the RegBack folder, copy the same files to the config folder.

Restart your computer from the installed OS. If there is a problem with the registry, then the sound may appear.

There are different models of motherboards that have special jumpers that redirect the audio signal.

Guess if you haven’t touched them recently and if so, turn them back to the exit position.

Before each system board contains documentation, look at the Audio section, you can find the necessary information there.

No codecs for audio/video

Situations are lost when the system sound is loud, and when I watch the movie on the video player, it disappears.

There is no need to panic, try opening this video file with another programmer, otherwise the problem may be in that one.

Or on your computer there are different codecs for decoding this type of video file. Videos also come in different formats.

If there are no codecs, then a solution is ready to easily import from the Internet, for example, K-Lite Codec Packs from the downloaded Media Player program.

While installing this package, select “Lots of Stuf”, and then everything will intuitively make sense.

Front panel

On some computers, speakers are connected through the front panels AC'97 (old) or HD Definition (new).

Check which connections are made to the system board and which type of panel the BIOS settings usually cost AC'97.

You need to try mixing and see the results.

Reinstalling the system

Reinstalling the system is the last resort you need to do. It’s not for nothing that we write about her like articles.

If you have decided on this last minute, then when you install new drivers on your computer, start with sound ones.

As a rule, drivers are installed on the motherboard first and if the sound card is integrated, sound may appear.

However, you will need to install an additional driver package for sound, which is included in the package.

Then new drivers are installed and after the installation stage the sound is checked.

So we know which of the devices creates a conflict.

If a conflict occurs, you will need to replace old versions of drivers with new ones, and also find those versions that work reliably on your operating system.

Also, don’t forget that you have to install a computer for your robot.

We pad the pouch

Well, we looked at the main reasons for the importance of sound on a computer and their versatility.

Of course, there may be other, complex situations, for example, problems with the system board or others. It’s more likely to turn violent towards the fakers.

We are confident that we will not get to that point, and you will be able to independently update the sound on your computer.

The sound on a computer is controlled by a software and hardware complex called the sound subsystem or audio system of the PC. All the stripes of this complex are closely intertwined with each other, and coming out in order, a small part is indicated on the work by a sign.

Without understanding it, it is impossible to definitely name the reason why there is no sound on the computer. There are also a number of problems: starting with a failure in Windows settings and ending with problems with sound path devices.

Before we talk about the reasons and how to fix it, let’s figure out what makes up the sound subsystem of a computer.

Equipment and software

Audio card

A sound card or sound adapter is a device used for processing audio data on a PC. Cards can be discrete (discrete) or integrated - soldered on the PC motherboard. The rest is most extensive and is represented by two basic elements: an audio codec - a small 4x4 mm microcircuit, and a host controller near the chipset (on the bridge).

Attach the recording and creation

Software related to audio

• The driver that drives the audio card. Since there is no driver, there is also no sound on the computer.
• Adjustment utilities: “Sound” for Windows and audio device managers from hardware distributors.
• System services: Call up the end points of Windows Audio.
• Codecs are a set of dynamic libraries necessary for creating audio files of different formats. Some audio codecs are available in Windows initially, others are installed as required. The absence of some codecs is due to the fact that music files cannot be opened on the computer, but overall the sound does not disappear. Example codecs: mp3, wma, aac, etc.

Let's find out why there is no sound on a computer or laptop

To make it easier to understand why the computer quickly became deaf and mute, we can divide the reasons into 2 groups at a time:

• there was no sound on the PC from the moment of purchase or installation of the system;
• the sound came after I had worked.

There was no sound at all

Connecting speakers

First check to make sure the audio card is installed and plugged in correctly. Look at the rear end of the system unit - the jacks for the microphone, speakers and headphones are located either on the motherboard, or a little lower - where the sound card is connected as an extension. There are at least 2-3 such sockets (microphone input, line input and line output), or at most a dozen (on professional cards). On laptops there may be only one jack 3.5 socket.

Besides the audio card, due to the fact that there is no sound on the computer from speakers or headphones, it’s better to switch from the very beginning so that you can check them on another PC or on your phone. Without harm, if you check the speakers in the skin socket, the fragments of the socket can be reassigned in the settings of the audio device manager.

Let's see how this reassignment works in the Realtek utility application:

• Open the Realtek HD Manager panel
• On the right side of the window there is a diagram of audio connections. Right-click the mouse on the one you want to re-recognize
• Select “Change of the designated nest”

• From the window that has opened, select the device you want to connect to this socket

Install the driver

Go to Device Manager and make sure the sound driver is installed. Without a driver, the audio card will be recognized as an unknown device. Open the device manager panel and go to what it is. Either way, install the sound driver that you find on the disk of your motherboard or laptop, or download it from the manufacturer’s website. Most audio cards are also equipped with discs with software, so there are no problems with them.

If you have a similar picture in your mind (and the list of sound devices does not have an audio card), this is your fault. For sound to appear, the driver must be installed. It can be found on the disk on the motherboard, but if there is no disk, you can download it from the manufacturer’s website. Or from the sound adapter manufacturer's website, if your model is available.

How to find out the required driver for your motherboard model

To begin with, you need to identify the “mami” model. Who can help with one of the utilities for recognizing the ownership of a PC, for example, the hardware-free HWiNFO3264 or CPU-Z. For HWiNFO, the required information is displayed in the System Summary window, in the Motherboard field.

For CPU-Z - on the Mainboard tab in the Model field.

• In the list of services, find “Set up the end points of Windows Audio” and open their power (the same item in the context menu). In the “Zagalni” tab, you need to select the “Automatic” startup type. If the service is running, click the “Start” button

Setting up the BIOS

Then you need to re-convert so that the card is not stuck. The parameter associated with sound can be called: “Audio Controller”, “Azalia Audio”, “HDA Controller”, “OnChip Sound” or with the words sound, audio, azalia, HDA. For different BIOS versions, these are located in the Advanced or Integrated Peripherals tabs. To turn off an audio device, you need to set it to Auto or Enabled.

We connect a valid audio card

Is the computer still “deaf”? It is not disabled because the sound card is simply faulty. There are a lot of inexpensive discrete audio cards on sale with USB, PCI and PCI-E interfaces, which can replace the one supplied with any device.

Previously, the sound was buv, ale znik

Please note why the sound on the computer after normal operation becomes even more complex. Here we get to the names of the reasons.

Virus infection

The virus can not only steal or zip your data, but also shut down your computer without sound. The problem is caused by the activity of various programs and changes in the system that vibrate (modification of system files and the registry by viruses and Trojans is a common occurrence).

First of all, it is clear that it is necessary to get rid of malware - for which the antivirus that “normally” operates in the system often lacks the capabilities. And if the shower did not help and the sound did not appear, you will have to renew the Windows robot (at a lower price).

Defects in system files or registry sections associated with sound

At the same time, troubleshooting problems with files and the registry will help, since before the sound is heard, a checkpoint has been created.

If the point is missing or this function is disabled, you can try to correct the situation using other system mechanisms:

• updating files using the Windows utility sfc.exe;
• Updating the registry from backup.

Procedure for updating files using SFC:

• Run Command Row (cmd.exe) as administrator
• Write to her: sfc /scannow(which means check the system files, and if there are changes, automatically update the settings) and press Enter.

Registry update

The current (obsessions) register is kept by the father C:\Windows\System32\config. It consists of five files without extension: default, security, sam, system and software. A backup copy of the registry, which looks like five files, is saved in a folder in 7, 8 and 8.1 C:\Windows\System32\config\RegBack. The skin is automatically renewed for 10 days.

Windows XP does not have this - it only has a copy of the registry saved immediately after the system is installed. Vaughn is a dad C:\Windows\Repair.

If there are problems, including those related to sound, you can improve the efficiency of Windows by replacing the stream registry files with a backup one. Thankfully, if this was done earlier, the problem would be solved.

How can you earn money?

• Use a computer from another device (for example, a Live CD, an explorer or a file manager - Midnight commander, FAR, etc.)
• Go to C:\Windows\System32\config and add five files to the registry extension.old
• Go to C:\Windows\System32\config\RegBack (on XP - from C:\Windows\Repair), copy the same backup copies and place them at C:\Windows\System32\config
• Restart your computer from the hard drive - Windows will recover the old registry and the problem that was in the new one will persist.

Rozgin computer

Overclocking the computer - if you go to the BIOS and change the settings there, it can lead to problems with sound. It is not written in the instructions for overclocking that if you paint one, you can paint another.

If you have such little space, then setting up the BIOS will need to be skipped. For whom you can vikorist, be it in any way possible.

• Go to BIOS Setup and on the Exit or Save & Exit tab click Load Setup Defaults (Load Defaults BIOS, Load Safe-Fail Defaults, Load Defaults Settings, Set BIOS Default, Restore Defaults - the names of the options vary for different BIOS versions).

• Find the RTC battery on the motherboard (on motherboards of stationary computers it is a “tablet” CR2032) and remove it from its socket every hour (15 – 30 hours). For faster removal, you can insufficiently close the battery socket.
• Find the Clear CMOS jumper on the board (CLRTC, Clear RTC, CCMOS, etc. - the names are different on different boards) and move them unnecessarily to the 2nd contacts.

The second and third way can only be completed when the computer is turned off completely (from the socket or with a button on the power block).

Why else can you not have sound on your computer?

If the jumpers on the motherboard, which indicate that the output is over-assigned to sound, are not installed or are positioned incorrectly, there will be no sound! It is important to carefully follow the instructions on the motherboard that connect Audio, and check how to set the jumpers correctly. In this case, the symptoms are as follows: the file is being processed by the programmer, the volume is set correctly, but there is complete silence in the speakers.

If you connect to the front panel, it may simply not be connected to the payment or it may be connected incorrectly. There are two types of front panels: old AC'97 and HD Definition. Apparently, since the BIOS settings are also configured, you need to select the type of your front panel (try both).

However, the instructions are too complicated or it is not possible to solve the problem, and also, if the situation repeats itself, it is better to do it first - go to the service or write about your problem in the comments before the article.

The computer has long since ceased to be an inclusive device for robots and calculations. There are a lot of koristuvachs who vikorist in their own way: marvel at films, listen to music, play games. In addition, with the help of a PC you can contact other traders and get started. This works better for such musicians under the musical supervision. If you don't use your computer, you may encounter a problem such as lack of sound. Let's figure out what you can do and how to access it on a laptop or desktop PC running Windows 7.

The understanding of sound on a PC can be divided into different settings, but they can be divided into 4 groups:

• Acoustic system (speakers, headphones, etc.);
• PC hardware;
• Operating system;
• Programs that create sound.

The remaining group of officials at the statistics see nothing to understand, since this is a problem with a specific program, rather than a legal system. We are concerned about the most complex problems with sound.

In addition, it is necessary to note that sounds can arise both through various breakdowns and malfunctions, and through incorrect adjustment of reference components.

Method 1: sound system malfunctions

One of the common reasons why the computer does not produce sound is problems with the acoustics that are connected (headphones, speakers, etc.).

1. Thank you for everything, make this reversal:
   • whether the speaker system is correctly connected to the computer;
   • turn on the plug until the power supply is reduced (if such power is transferred);
   • whether the sound device itself is turned on;
   • If the volume control is not set to the acoustic position “0”.
2. Since this is possible, consider the effectiveness of the speaker system on another device. If you use your laptop with headphones or speakers connected, check how the sound is output from your computer's speakers.
3. If the result is negative and the acoustic system does not work, then you will need to contact a qualified master or simply replace it with a new one. Since on other devices it produces sound normally, it means that on the right there is no acoustics and we move on to the next options for the worst problem.

Method 2: icon on the task panel

The first thing to look for is a malfunction in the system, it is important to check that the sound on the computer is not muted using standard tools.

This is also possible if the groups cross each other every day, but the sound is still mute.

There is also an option if at the same time there is an icon that looks like a crossed stake and a regulator for the intensity of lowering to the bottom. In this case, it is necessary to carry out the offensively designated manipulation.

Method 3: drivers

If there is a problem with sound on your PC, there may be a problem with the drivers. They may be installed incorrectly or burn out during the day. It is best to install the driver from the disk that came with the sound card installed on your computer. To do this, you need to insert the disc into the drive and after starting it, follow these recommendations as they appear on the screen. If you have a disk for any reason, it is subject to current recommendations.

1. Click "Start". Next, you will make movements to "Control panel".



2. Go to "System and security".



3. Far from the section "System" go to subsection "Device Manager".

   

   You can also go to Device Manager by entering a command in the tool field "Viconati". Click at the end "Viconati" (Win+R). Enter the command:

   Onslaught "OK".



4. The Device Manager window opens. Click on category names “Sound, video and game devices”.



5. In the drop-down list you will find the name of the sound card that is installed on your PC. Click on it with the right mouse button and select from the list "Onoviti drivers...".



6. It starts at the end when you make a choice to update the driver: do an automatic search on the Internet or enter the route to the previously installed driver installed on the PC’s hard drive. Choose an option "Automatic search for updated drivers".



7. The process of automatically searching for drivers on the Internet begins.



8. Once updates are found, they can be installed.

If the computer is not able to detect updates automatically, you can search for drivers manually via the Internet.

1. To do this, simply open your browser and enter the name of the sound card installed on your computer into the search system. Then, from the sound view, go to the web resource of the sound card manufacturer and download the necessary updates on your PC.

   

   When you name a sound device in the Device Manager, there is a viguku sign, which means that it is working incorrectly.

   
   

   Method 4: upgrading the service

   On a computer, sounds can be made daily and through those that the service that represents its creation is enabled. Let's find out how to use it on Windows 7.

   1. To check the functionality of the service and if you need to enable it, go to Service Manager. For whom click "Start". Press further "Control panel".

   

   2. Click on the window "System and security".

   

   3. Then go to the item "Administration".

   

   4. The list of tools opens. Upload your choice to the hired one "Services".

      

      The Service Manager can be opened in another way. Dial Win+R. Launch at the end "Viconati". Enter:

      Press on "OK".

   

   5. In the list that has opened, find the component under the name Windows Audio. Yakshcho near the field "Launch type" worth a lot "Disabled", but not "Pratsuє", which means that the reason for the absence of sound is precisely at the point of service.

   

   6. Click the left mouse button on the component names to go to its power.

   

   7. In the window in the section "Zagalni" Quit it, please "Launch type" obov'yazkovo standing option "Automatic". If a different value is set there, click on the field and select the required option from the list. If this is not possible, then after restarting the computer you will notice that the sound disappears again and you will have to start the service manually again. Then press the button "OK".

   

   8. After returning to the Services Manager you will see again Windows Audio And in the left part of the window, click on "Run".

   

   9. The process of starting the service is completed.

   

   10. Please continue to perform this service, so please check the attribute "Pratsuє" in the field "Mill". Also show respect, so that in the field "Launch type" the value was set "Automatic".

   

   After you select these actions, a sound may appear on your computer.

   Method 5: checking for the presence of viruses

   One of the reasons why sound does not appear on the computer may be a virus infection.

   As practice shows, once a virus has made its way onto a computer, scanning the system with a standard antivirus is ineffective. This problem can be helped by a special anti-virus utility with scanning and detection functions, such as Dr.Web CureIt. Moreover, it is better to carry out scanning from another device, first reaching the PC, before any suspicion of infection. In extreme cases, when it is not possible to perform a scan with another device, use a special nose for the final procedure.

   

   Before the scanning procedure, select the recommendations provided by the anti-virus utility.

   Please note that if you can successfully eliminate the corrupt code, the sound update is not yet guaranteed, since the virus may corrupt the driver or important system files. In this case, it is necessary to reinstall the drivers, and also, if necessary, update the system.

   Method 6: update and reinstall the OS

   As a result, it is expected from the descriptions of methods without giving a positive result and you have decided that the cause of the problem is not in acoustics, but rather a sense of updating the system from a backup copy or going to the current update point. It is important that the backup copy and update point be created before the sound problems begin, and not after.

   
   

   

   If you don’t have a system update point on your computer that was created before you installed a sound and a daily backup with a backup copy, then you will have to reinstall the OS.

   Method 7: sound card malfunction

   If you have definitely followed all the descriptions and recommendations, but after reinstalling the operating system the sound does not appear, then we can say with great certainty that the problem lies in the malfunction of one of the hardware components of the computer. Yutera. During the entire period of sounding, the sound card was broken.

   In this case, you need to either seek help from the emergency department or independently replace the faulty sound card. Before replacing, you can first protest the usefulness of the sound element of the computer that was acquired from this computer.

   However, there are many reasons why sound may occur on a computer running Windows 7. Before you solve the problem, it’s best to identify the root cause. If you can’t work it out right away, try to set various options for correcting the situation using the algorithm specified in this article, and then check if the sound does not appear. The most radical options (reinstalling the OS and replacing the sound card) should be used when other methods have not helped.

Vikoristovvati computer without a sound system is even more comfortable. One on the right, there are some additional system signals, and completely different ones – “no” games, movies and music that you can play. Today we will look into the problem if there is no sound on a Windows 7 computer: what to do and why to find out the reason. And you can cry in different places:

• Adjusting the sound;
• Parameters of development devices;
• Sound card station;
• Problems with drivers can also be the reason why the sound is lost.

What to do if there is no sound on your computer in Windows 7

Turn it over first and turn on the sound. There is a symbol in the tray on the speaker icon that blocks, which means the sound is muted for everything.

How can I become active? Click on the icon, and then on the connection symbol.

At the same time, increase the thickness, otherwise the weakness may not be noticed.

When you turn off the sound on your computer with Windows 7, turn it over so you don’t lose it and then press the Mute key. On some keyboards there is such a button, and on laptops there is a similar Fn button.

Mixer connections: how to turn it off

The mixer is set for more fine-tuning of parameters. The advantage lies in the fact that it can be used as a way to get sound for several programs (ideal for games) - or you can turn everything back.

Right-click the speaker icon to open the menu, then select mixer.

You are now aware of the configured sound for devices on your computer and programs for Windows 7.

The volume can be completely turned off or set to 0 for the purpose of the program in which you “wasted” the sound.

Physically damaged or faulty speakers/headphones

It can be easily verified in any OS, including Windows 7, because the reason why there is often no sound on the computer is a malfunction of the speakers or headphones, which will cut off the connection. Try connecting others, obviously.

Check where the cord is connected: the sound card can have a number of outputs, the main one of which is green. And turn the jumpers on the device itself - the speakers at the back may have a mute button or turn the volume control to zero.

Silent theme enabled

If there are any system signals on your computer, such as the sound of a computer, you can install them in Windows 7. Right-click on the speaker icon in the notification area and select “Sounds” "

The window with settings will open. If the silent option is selected, click on the menu that appears.

Choose a suitable scheme for Windows 7 – who loves quiet sound and wants energetic signals on the computer.

Or adjust the signals around.

Save your money.

Vimkneno installations

Another option is to adjust the sound on your computer using the standard Windows 7 methods, leading to “sounding”. To check it, open sound devices through the option in the indicator context menu.

It is possible that the sound does not appear for the same reason that all the devices that are on the computer are connected and Windows 7 does not show them in the list.

In this case, select the additional menu by right-clicking and click on them.

After this, you will become active and you will be able to play music. Just turn it on, Windows 7 allows you to adjust the sound both on your laptop and on your PC.

Here you can also look at the hint on how to configure the roses.

If the sound on your computer is interrupted, stutters, or otherwise interferes, look at the other tab and try selecting a different format for Windows 7.

Windows Audio service does not work

If there is a sound, it is possible that the service has turned on, which is indicative of him. To check, launch the Task Manager.

Find the service again in the window and click on it.

Click the “Launch” button, select the automatic mode for activation (otherwise) and set the new parameters.

Daily or faulty drivers

To program, you need to install a driver for audio devices. Open the system device manager to check - it’s easy to find out by its name by searching the Start menu.

Open the device with sound devices. Try updating the drivers first - it is possible that there was a bug during installation or the system incorrectly identified the components required for correct operation. You should also check the availability of patches for the OS at the Update Center (the shortcut is in Pusku).

Drivers can be downloaded directly from the website of the manufacturer of your PC or laptop; in this case, you need to select them according to the device model. You can also use third-party programs (driver packs) on your computer to select the required software for system sound, such as finding new versions of drivers for Windows 7.

Before speaking, on some laptops (including ASUS K50C) “Simtsa” suffers from galvanization and other problems with the correct drivers. In this case, you can use the SRS Audio Sandbox program. Turn it over, perhaps, and in your case there will be no malfunction.

No codecs

Since Windows 7 is only installed on the computer, problems with quiet sound or constant availability may be due to defective codecs. In this case, you can install a third-party player that contains all the necessary components - VLC would be a wonderful option. Or you can install a third-party set, such as the K-lite codec pack, which in the Basic version includes some popular codecs.

The influx of viruses

Some nasty programs interfere with the normal operation of audio devices. Therefore, turn over your computer using CureIt or other reliable anti-virus programs.

Incorrect BIOS settings

If the headphones do not work when connected to the front panel or the built-in sound card does not function, then the reason may be BOIS. You can get into this by pressing Del or another key when starting the PC before the OS is installed (search Google for your computer model or motherboard). Look at the settings, find the onboard audio icon and set the new value to Enabled. There you can make adjustments for the Front panel (from the front).

Sound card is faulty

Sometimes these methods do not help. In this case, it is possible that the sound card itself has stopped working. To check it, you need to immediately connect the other one.

Compact and inexpensive USB models are available.
