What to do the sound drivers. The five main causes of the lack of sound in the computer. Reinstalling sound drivers

Hello.

I never thought that with sound could be so many problems! It is indisputable, but this is a fact - a sufficiently large number of laptop users are faced with the fact that one day, the sound on their device disappears ...

This may occur for various reasons and, most often, the problem can be eliminated independently, fighting in windows settings and drivers (thanks to which, save on computer services). In this article, I collected some of the most frequent reasons why the sound on laptops disappears (check and eliminate which even the novice user of the PC!). So…

Cause # 1: Adjusting the volume in Windows

Of course, I understand that many can express discontent - " that it is quite ...»For such an article. But all the same, many users do not know that the sound in Windows is regulated not only by the slider, which is located next to the clock (see Fig. 1).

Fig. 1. Winows 10: Volume.

If you click on the sound icon (located next to the clock, see Fig. 1) Right-click - then several will appear additional options (See Fig. 2).

  1. mixer Volume: It allows you to set your volume in each application (for example, if you do not need a sound in the browser - it is possible to turn it out there;
  2. playback devices: In this tab, you can choose through which speakers or speakers to play sound (and in general, in this tab, all sound devices connected to the device are displayed. Moreover, sometimes even those you do not have! And imagine, sound can be served on non-existent devices ...).

IN mixer Volume Please note whether the sound is not reduced to a minimum in your running application. It is recommended to raise all the sliders up at least for the time of finding the causes and troubleshooting with sound (see Fig. 3).

In the tab " Playback devices"Please note that you have maybe several devices (I have in fig. 4 just one device) - and if the sound "serves" is not the device, it may be the reason for the loss of sound. I recommend you check all devices displayed in this tab!

Fig. 4. Tab "Sound / Playback".

By the way, sometimes understand and find the causes of problems with sound helps the built-in Windows Master. To start it - simply, right-click on the sound icon in Windows (next to the clock) and start the appropriate master (as in Fig. 5).

Cause # 2: Drivers and their setup

One of the most frequent causes of problems with sound (and not only with it) are conflicting drivers (or the absence of these). To check their presence, I recommend to open device Manager: To do it enter into panel windows management , then switch the display to major icons and run this dispatcher (see Fig. 6).

Next, open the " Sound, Gaming and Video Devices". Pay attention to all lines: there should be no exclamation of yellow signs and red crosses (which means that problems are observed with the drivers).

By the way, I also recommend checking the drivers in the Driver Booster utility (there is both free and paid version, differ in speed). The utility easily and quickly helps to check and find the necessary drivers (an example is shown in the screenshot below). What is convenient - so this is what you do not need to independently search for various software sites, the utility itself will compare the dates and find the desired driver, you will also remain just pressing the button and agree on its installation.

Cause # 3: Not configured Sound Manager

In addition to the sound settings in the Windows itself, there is a sound manager in the system (almost always), which is installed with the drivers ( in most cases, this is REALTEK HIGH DEFINITION AUDIO). And quite often, it is in it that may not be set optimal settingswho do no sound audible ...

How to find it?

Very simple: come in windows Control Paneland then go to the tab " Equipment and sound". Next, this tab should see the dispatcher, which is installed on your equipment. For example, on a laptop that I am in this moment I set up - installed Dell Audio application. This software needs to be opened (see Fig. 10).

Another important point: you need to check whether the laptop correctly determines the device connected to it. For example, you inserted headphones, and the laptop did not recognize them and work incorrectly with them. Result: There is no sound in headphones!

So that this is not - when connecting the same headphones (for example), a laptop, usually asks if he determined them correctly. Your task: Specify him correctly the audio device (which you connected). Actually, it happens in Fig. 12.

Cause # 4: Work is disabled sound card in bios.

In some laptops, you can turn off the audio card in the BIOS settings. So you are unlikely to hear the sound from your mobile "friend." Sometimes bIOS settings may be "random" changed in impudent actions (for example, when windows installation Not experienced users often change not only what they need ...).

Actions in order:

2. Since the settings in the BIOS differ depending on the manufacturer, then give universal instructions quite difficult. I recommend to go to all tabs and check all items in which the word "Audio" is present. For example, in Asus laptops, there is the Advanced tab, in which you want to translate into Enabled mode (i.e. included) High Definition Audio string (see Fig. 13).

Fig. 13. Laptop asus - BIOS settings.

Cause No. 5: Lack of some audio and video codecs

Quite often, the problem is observed when you try to play some movie or audio record. If there is no sound when opening video files or music (but there is no sound in other applications) - the problem is 99.9% related to codecs!

  • first delete all the old codecs from the system completely;
  • next restart the laptop;
  • install anew one of the following sets (find the link) in full extended mode (so you will have all the most necessary codecs in the system).

Codec Sets for Windows 7, 8, 10 -

For those who do not want to establish new codecs to the system - there is another option, download and install a video player, which already contains all the most necessary to play the files different types. Such a player becomes quite popular, especially in lately (and not surprising, who wishes to suffer with codecs?!). Link to an article about such a player will find below ...

Players working without codecs -

Cause # 6: Problem with sound card

The latter on what I wanted to stop in this article is on the problems of a sound card (it can fail with sharp electricity jumps (for example, with zipper or welding)).

If this happened, then in my opinion, the most optimal option - Use an external sound card. Such cards are now available at the price ( especially if you buy in some Chinese store ... at least it is much cheaper than looking for "native") And represent a compact device, the size of a little more than the usual flash drive. One of these external sound cards is presented in Fig. 14. By the way, such a card often provides sound much better than the built-in card in your laptop!

PS.

I finish on the sim article. By the way, if you have a sound, but it is quiet - I recommend using tips from this article :. Good job!

The problems associated with playing sound are not uncommon. Their nature can be a variety of: a damaged or not included service, the wrong driver, which failed the sound chip on the motherboard, the virus, the outgoing contact of the dynamics or headphones (in this you should make sure right now). In this article, we will discuss what could be the reason that sound disappears in the system, that is, the media files are reproduced normally, but after a while they cease to do it. Listed all the reasons starting with hardware and ending with problems with codecs and drivers.

To make sure that the sound disappears not because the audio chip wants to "give the soul to God", try to boot from any Linux Live CD with full graphical interface, for example, Ubuntu the most recent version and make sure the sound is running. Use this distribution multiple sessions to catch the hardware disappearance of the sound if it is. It is clear that if the sound disappears in Linux, you should replace the built-in outer, the problem will be solved (do not forget to disable the built-in BIOS). It is also necessary to make sure that the motherboard does not "run". Look, whether there is no condenser on it.

Only after determining the program nature, the problem can be achieved for business. A frequent reason that the sound disappears in Windows XP is a malicious software. Therefore, download the antivirus with the latest databases, a DR Web Cure It is excellent for this purpose, boot into safe mode with the support command line And carefully check the system.

It is also recommended to use Antivirus Zaitseva (AVZ), specially created for cleaning a PC from a similar cunning "unclean" (one of the manifestations of the ancient NET-Worm.Win32.kido). For Windows XP, when specified symptoms, install windows Update XP-KB958644-X86-RUS, after cleaning the PC from viruses and with a disabled network. Also via the "Services" section of the "Administration" icons should be disabled "Server" and the working "station". For the future, the ports should generally close through which this virus penetrates. Good decision Will use Windows Worms Doors Cleaner (wwdc.exe), fully closing ports 5000, 445, 135, 137,138,139 and preventing the system infection in the future. Do not believe you, to your naivety, that all vulnerabilities on these services have already been found?!

And more modern systemsthan XP, it happens that Windows 7 is no exception. All that is listed below should be taken on the "seven" to locate and eliminate the malfunction associated with the impossibility of playing media files.

Remember when the problem first manifested itself. If it succeeds, then make a rollback to the recovery point before the date. If there is no reason for some reason, then open (Win + Pause\u003e Tab "Equipment"\u003e Device Manager button) and make sure that there are no devices in front of the devices. If they are still there, then delete them and restart Windows. Virtual devices Must "find", and the sound to earn.

If it did not help, then install the most new version Drivers for your find out the version of the chip can be from the documentation for the motherboard. The most common codec - Realtek AC 97. Another frequent reason that the sound disappears - "fallen" windows service Audio. You can see it through the "Administration" panels icon. It can for some reason do not start. You can see the reasons with the help of the "View Events" item. Then drive the error number in the search engine and get a description of the problem and measures to eliminate it on the Microsoft website. It should be noted that the most common error is 1068, which the system issues in the absence of the "power supply".

Quite often, if the sound is disappeared on the computer only in the video, there is a problem with codecs. To eliminate it, use one of the stable FDShow assemblies, and not popular collections K-Lite Codec Pack, composed of non-professional.

For the sound and playback of audio files on a computer with Windows XP - 10, software and hardware are responding. It is because of their proper functioning and interaction it becomes possible to watch movies, listen to music, play games, process audio data. But when one of these components is not or it works in non-standard mode - the entire chain is broken and, as a rule, sound disappears on the computer. Today we consider what to do if sounded sound on Windows and how to determine the cause of the problem.

Components responsible for playing audio

The hardware processing of audio files includes:

  • sound or audio card. It can be both integrated into the motherboard (in most cases) and discrete (the expansion board is connected to the PC separately). A sound card is a set of microcircuits with its own controller, chipset, multiple ports for connecting devices.
  • external devices for sound playback. These include columns, acoustic systems and headphones.

Software components, incorrect operation or configuration of which leads to the fact that there is no sound on Windows XP - 10:

  • sound card drivers - a set of system programs that allow you to control the functioning of sound, sound card and its interaction with the operating system;
  • audio Windows service - allows you to reproduce the sound of applications and operating wINDOVS system from xp to 10;
  • audio codec - a set of software libraries that allow you to encode and decode audio data. It is the codec that is responsible for processing the audio file, its decoding and transmission to the application to play. If it is not - there is no sound on the computer.
  • sound control programs are usually supplied with drivers. With their help, it is configured to adjust the volume, equalizer and overlay audio effects on audio in Windows XP - 10.

Causes of signal disappearance

Based on the above, the answers to the question "why sound sounded on a computer with Windows XP?" May be set. These are both problems in the operation of hardware and improper configuration of software components. If the sound disappeared after reinstalling the operating system - the reasons for some, when there are no audio in films - completely different. Next, consider possible factors disappearance of sound on your computer.

Possible reasons for which many users have sounded sound on Windows 10:

  • Sound equipment is disabled or incorrectly connected.
  • There are no audio codecs and / or sound card drivers.
  • Windows Audio is removed from autoload or not started.
  • Incorrect system setup: Sound functioning is disabled in the BIOS or Task Manager , more precisely, audio fees.
  • Damage or modification system files Windows 10, for example, virus.
  • Changed the volume adjustment in the system to zero.
  • Invalid application configuration (the wrong sound card is selected if there are two).

Checking hardware components

We are convinced that sound playback devices are properly connected.

Cable from speakers, headphones or acoustic system Must be connected to a green connector on the rear wall of the housing. You may have connected Jack by negligence not to that connector because the sound and disappeared. When using the output on the front panel of the case on the computer, you must make sure that it is connected to the motherboard.

  • Then the sound level is configured.

Perhaps the volume of speakers or sound in the system with Windows 10 is mounted on a zero mark or acoustics is not connected to the network.

  • Restart PC and click Del or F2, in order to enter the BIOS settings. Through the keyboard cursor block, go to "Advanced" and find the item "Audio Controller". Its value should be "Enabled".


We solve problems with software

The factors associated with the problems of the software shell, which caused the disappearance of the audio on the PC with Windows 10 significantly more, and consider them.

Drivers

  • Go to the "Task Manager" through context menu "My computer".
  • We deploy "sound, video, gaming devices" and check the presence of an audio driver and audio board activity.

  • In the absence of the installation package from the manufacturer's official website and install the driver, or call the context menu of the unknown equipment, we go to the "Details" tab.

  • Select the "instance code" and copy its buffer.

  • We go to the Devid.info website and insert the contents of the buffer into the search string.
  • Download last version Drivers and unpack the archive.
  • Call the context menu of an unknown device, click "Update" and specify the path to the contents of the downloaded archive.

Driver failure

If the sound icon with an exclamation mark is displayed in the taskbar, it means that you need to configure or reinstall its driver. We go into the properties of the audio payment in the "Task Manager" and delete the driver. After rebooting Windows 10, it will be installed automatically if not - we are installed manually.

Often, users encounter such a problem when sound suddenly disappears on Windows 7. Causes can be completely different. Depending on them, the solutes of solving the problem are different. It is important to understand that any information related to your computer will help to solve it. Frequently faced with this problem:

  1. Attempt to update the driver for a sound card or any other.
  2. Connected other columns to the device.
  3. Reinstalled the Windows operating system.
  4. Changes were made by system settings, registry.
  5. Installed additional software To improve the computer.

If your sound card perfectly worked before reinstalling Windows, and now gives a failure, then the problem most likely lies in the drivers. In this case, the volume can be displayed quite safely, and the volume icon may be displayed, and after reinstalling Windows Will notify you that I installed all the drivers. However, it does not mean that the drivers were installed correctly and are suitable for your sound card.

To fix it this problemYou need to do the following:

  1. If you have a laptop, then just go to the manufacturer's official website and download the latest version of the drivers for your model (this is a whole package of updates, so you will not have to look for a specific driver);
  2. You can also search the disk with all drivers, which usually goes complete with a computer and other discs (for example, to install Windows).
  3. If you have a landline computer, then you need to know the model motherboard.
  4. Then go to the official website of the motherboard manufacturer (that is, not your sound card or audio chip) and download the driver of the drivers from there.
  5. After the actions of the actions and the installations of the drivers do not forget to restart the computer.

Checking the correctness of the connection and operability of columns

To figure out why sound disappeared on a computer, although yesterday it was, we consider some of the main points. First, check if your speakers or headphones are enabled correctly. It is possible that someone from your family members accidentally turned off the speaker or stuck the plug is not at the nest.

In any case, check again whether the speakers and other equipment on the computer are properly connected.

If you are confident that everything is connected correctly, try checking the speakers themselves. To do this, connect them to another device: player, telephone or TV. If they work, then the problem is in the computer itself.

Windows settings

The next thing to do is to find the volume icon in the tray and click on it with the right mouse button. The context menu appears. It is necessary to select the "Playback Device".

In the window that opens, check which of the devices is used as an audio output (that is, playback devices, not record). By default, it must be computer dynamics. All the necessary information about the sound card on the computer will also be indicated here. If you are using an additional audio markup (USB), then it is currently it is used as the default device, so change it to external speakers.

If a device for playback is selected correctly, you will select speakers in the list and go to the "Properties" tab. Here carefully view each individual tab:

  1. general (information about an audio map will be indicated here, while by clicking "Properties" and by going to the Driver tab you can check the availability and date of the installed software) Ensure that the "Application Device" clause is "use";
  2. levels (check that the volume slider does not stand at the minimum one);
  3. improvements (preferably disable all effects);
  4. SRS Audio Enhancement;
  5. additionally (here, click on the green triangle "Check", an audio signal should appear, check that the default format is "16 Bit, 44100 Hz").

If all settings are set correctly, but there is no sound on the computer, then we are looking for the root of the problem further. In addition, if you use a special software to set up an audio system, check all the settings there.

In reproduction devices empty

If you enter the playback device on the computer, you found that there are absolutely no devices, then you need to do the following:

  • Right-click on your empty space.
  • The context menu appears.
  • Mark two items: Show disabled and disconnected devices.

After the actions done, all your audio devices should appear in the window with the "Disabled" mark. Therefore, we click on the speakers with the right mouse button and choose "Enable".

Similar actions are carried out with other devices, such as headphones. If you managed to do everything right, there should be no problems.

Playback devices are turned on, but there is no sound

It happens that in front of the playback devices, a green tick is displayed, notifying the device's performance, but there is no sound anyway. Connect other headphones or columns to the computer again. Audio signal still not? So the problem is not exactly in the columns. We continue to look next. Perhaps the drivers on the audio card were incorrectly set. Therefore, it will be useful to remove them again and re-put. In order to do this, you need to get into the Device Manager. Therefore, open the start and enter the "Device Manager".

Or open the toolbar, go to the "Equipment and Sound" block, and then "Device Manager".

The Device Manager itself opens. Here you need to delete all the sound drivers installed on your computer. To do this, click on it right-click and select "Delete".

After you delete all audio resources to restart the computer. Immediately after switching on, it will automatically begin to search for missing drivers and their installation.

Usually, this procedure helps to return the sound. Also solve this problem, you can restore the system.

In Device Manager, incomprehensible characters

The next problem when the user installed on his windows computer 7 And everything except audio works fine. If you run the device manager, then the following icons will be near the drivers.

Usually means that installed outdated drivers (You have Windows 7, and the drivers set for XP). If you do not have the ability to download other drivers, then to correct the problem, you need to do the following:

Turn on the sound in BIOS

It also happens that the virus or any other fault simply disables the audio card in the BIOS settings. To make sure everything works, you need to do the following:


Checking the health services

The next thing you can check is whether the Windows Audio service works on the computer. To do this, you need:

  • Open "Start" - "Control Panel".
  • Select the system "System and Security".
  • Open "Administration" - "Services".

For a more convenient search, sort the name by name. Find the "Windows Audio" line.

Make sure this service is enabled. To do this, we see the information in the status "Status" - must be "working", as well as the type of launch "automatically". If something out of this is indicated, then we click on it right mouse button and change the parameters you need.

After that, do not forget to restart the computer. If it does not help, we go to desperate measures and try to use the built-in Windows utility trouble finding problems.

Windows diagnostics

Many users are critical enough to have this function. Nevertheless, it cannot be underestimated. Especially in cases where, it seems that nothing helps. To proceed with the diagnosis, you must do the following:


An additional dialog box opens where you can choose specific region To search and troubleshoot problems. Since we are trying to configure the sound now, we select the corresponding "sound and equipment" block.

Then the "Playback" item.

You will have a built-in service for searching and eliminating windows troubleshooting. To get the utility to work for you to click "Next" and wait for its results.

If Windows succeeds to find the source of the problem, it deals independently the missing drivers or return the default settings. You will only stay to restart the computer.

Malfunction of audioparticles

If no action does not help the above, then most likely your audio card or the other hardware failed. You can try to restore the system or full reinstalling windows. Especially if you are sure that the computer could not anything happen, and the problem appeared after you have installed a new operating system. Do not forget that the audio card is exactly the same part of the computer as rAM or processor. Therefore, it has its own limited validity period. Perhaps the fact that you disappeared the sound says that it is time to change it.

In contact with

Causes of lack of sound on a laptop are different. Sometimes they are pretty simple, and in other cases a malfunction has to look for a long time. In any case, before proceeding with troubleshooting, you will need to understand what exactly needs to be corrected.

Causes of lack of sound

Often the reason for the lack of sound on the laptop is precisely the actions of the user. For example, you downloaded new drivers or tried to update the already existing, but inexperienced or any other reason, did something wrong, after which the sound disappeared. Actually, one should not despair, because almost everything is fixable.

Quite often occurs that, since the sound card has failed. In this case, most likely it will be necessary to replace it. In addition, the problem may be in sound columns. Check if they are correct and securely connected. Also for sound output to join the headphones. If there is sound in them, then sound speakers are faulty. Now consider how to restore the sound on windows laptop 7, depending on the problem that originated.

What if the sound disappeared

So, let's go to the Start menu and select the control panel. Right-click You need to click on the computer, and in the list that appears, click Properties - Device Manager.


If next to the inscription Sound devices A yellow circle is drawn with an exclamation mark, then just flew the driver. Fix it can be installed new or update already existing ones. How to quickly update sound card drivers. Usually, a disk with utilities is attached to the laptop, so you just need to download them again.

In addition, a similar problem may occur in the event that you reinstalled the OS. Not always developers apply disk with the necessary drivers To laptop.
