There is no sound on the computer - what to do? Why is there no sound on my computer? Sound restoration The sound does not work on a Windows 7 computer

As it usually happens - “I’m sitting, not touching anything, listening to music, and then BAM and the sound is gone.” Well, or when you turn on the computer, the sound does not play.

Or maybe it’s not there when you enter the toy? In this article we will look at the possible reasons for the loss of sound. This may seem banal and familiar to some, but not everyone knows this.

1) We check the sound in another music player, simultaneously increasing and decreasing the volume in it.

2) We check the speakers/headphones with the volume control.

3) Checking the connection. Perhaps the wire has simply come loose (which should be plugged into the Green socket or with a picture of headphones).

4) Right-click on the Dynamics icon on the Taskbar in the lower right corner and select Open Volume Mixer and check everything there.

5) You can click on Speakers right there, a window will open in which you can “walk” through the tabs.

The correct operation of the audio will be indicated by a corresponding inscription under its name and a green check mark next to the device icon.

In particular on the tab Additionally there is a Check.

On Windows XP:

Start - Settings - Control Panel - Sounds and Audio Devices.

On the Audio tab, in the audio playback section, make sure your device is correctly identified and set to default:

Go to the Volume tab. Make sure that there is no checkmark next to the “Mute sound” item.

It is also necessary that the mixer volume be set above zero.

6) We do the same as in step 4, but select Playback devices.

7) Increase the volume directly on the Taskbar by clicking LMB on Speaker.

8) RMB on My Computer - Properties - Device Manager - look at the line Sound, video and gaming devices.

On Windows XP:

RMB on My Computer - Properties - "Hardware" tab and click "Device Manager".

Of course, everything there should be as on the screenshot, no exclamation marks.

You can do this: RMB on the device, select Disable, and then Enable again.

If there are exclamation marks, it means you need to update the drivers. Either through the installation disk, or in the way that I described in the article which video card is installed.

9) You can check the BIOS to see if this feature is disabled.

Due to the fact that their versions are different, I can only use my own example: the “Devices Configuration” menu item and the “High Definition Audio” sub-item - the switch opposite it should be in the “Enabled” position.

10) Start - Control Panel - Administrative Tools - Services.

We find our Windows Audio service, if it is turned off, then turn it on. The startup type should be "Automatic".

If turned off, then RMB and Properties.

11) Check the sound by connecting other speakers or headphones.

12) If you have several audio outputs (Green connectors), for example like me, both on the front of the system unit and on the back and in the speakers, check everything.

13) The worst point and the worst reason is that the sound card burned out.

Don’t forget to reboot after completing “events”.

Sometimes, due to certain life circumstances, it is necessary to install an operating system. Quite often, users discover that the sound has disappeared after reinstalling the system.

The possibility of a situation where the sound disappeared after installing Windows 7, unfortunately, is far from uncommon. Fortunately, it can be solved quite simply if you know exactly the reason.

Possible reasons

There may be several reasons for the sound to disappear. The main ones are hardware errors, that is, a malfunction of the sound card. In this case, you cannot do without specialized help. Or there are problems in the software, and specifically, in the lack of drivers for the sound card.

If the problem is with hardware, then you are unlikely to be able to solve the problem without special equipment and skills. Solving software problems is much simpler and does not require special knowledge and skills. To do this, you just need to confidently use the computer and not be afraid of it.

Solutions options

So, if after installing Windows 7 there is no sound, then the first thing you need to do is check the connection of the audio system to the computer, and also that the audio system you are using is selected in the settings. The check is as follows:

If the audio system is turned on and in use, but there is still no sound, then the most likely reason why the sound may disappear is that after reinstalling Windows 7, the drivers for the sound card or audio device were not installed. This problem is not so terrible and quite easily solved.

Finding and installing drivers

There are several ways to return sound after reinstalling Windows; the easiest way is to install control program distributions from the media that comes with the device; it contains all the necessary drivers. But if it happens that there is no disk, you can install the drivers using standard Windows tools.

So, to convince the OS to reinstall the drivers, follow the path indicated in the address bar of Explorer: “ Control Panel» → « system and safety" → "". And select " device Manager».

After completing these steps, the following window will appear:

In the window that appears, select “ Sound, video and gaming devices" and from the list that opens, select the desired system by double-clicking on the name. A properties window will appear in which you need to select the “ Driver».

In this window, you need to select the Update... button, and in the window that appears, click on the item “ Automatically search for updated drivers" After this, Windows will begin to search for the program on the Internet and update or install it if such a need exists.

Manual installation

If the built-in Windows service tells you something like “The installed software for this device does not need to be updated,” this does not mean that you actually have it installed and do not need to be updated.

If you just installed the system, then there are no audio drivers there. But the system simply failed. Also, quite often the automatic update service cannot find the necessary software, in this case the direct path is to manually search and install the necessary programs.

To do this, the first thing you need to do is decide which sound card you have installed. If your card is integrated into the motherboard, then most likely it is from Realtek, which means that you need to go to the manufacturer’s website and download the necessary software there. Device Manager identifies built-in cards as High Definition Audio Device.

But since you may have another audio card, it’s better to find out which one in advance. To do this we follow Start, we find " Execute" and write in the search bar " dxdiag" and click OK.

In the window that appears, go to the “ Sound" (sound).

Line " Name"(name) will tell you what card you have installed. After that, feel free to go to the manufacturer’s website and download the latest version of the software for your card.

After installing the software, restart the computer and check for sound.

Using driver packs

If you have already tried everything, but after reinstalling Windows 7 the sound still does not work, then you have two options. The first is to take the computer to a service center or use specialized software to install drivers, for example. It is better to download it from the official website.

After launch, the program will diagnose the system and indicate those drivers that need to be updated. It will also select the software recommended for installation. Among other things, it will contain Avast And Yandex browser, if you don’t need this happiness for nothing, find the button at the bottom of the window Switch to expert mode and manually configure what should be installed.

Feel free to install all the recommended drivers, but here are the software and programs that DRP suggests deleting, better viewing and changing the settings to those that suit you. The program may remove something you need.

Windows 7 Sound Service Problems

Sometimes the drivers are really fine, but problems arise because the audio service does not start. First, try changing the system sound a couple of times:

Hardware problems

If all the previous methods did not bring the desired result, then most likely there are problems with the hardware. An audio card may fail due to the failure of some individual elements, and not the entire board as a whole. But this will not reassure owners of integrated cards at all. The built-in cards are not repairable, so if it fails, you will have to buy a discrete sound card.

Discrete cards, as a rule, can be repaired, but you should not try to repair this device yourself without the appropriate skills and equipment; most likely, you will only aggravate the situation and spend much more money than if you gave the card to professionals.

Reasons for refusal:

overheat;
burnout;
raw contacts;
broken conductors;
broken plugs;
loose soldering;
developer error or manufacturing defect.

To extend the life of your computer, clean it several times a year. This will allow the cooling system to perform its function most efficiently and problems such as overheating and damp contacts will most likely not affect you.

However, the lack of sound is not always a consequence of the fact that the audio card has failed. The first step is to check the functionality of the audio system; to do this, simply connect other speakers to the computer.

Also, cords can fail, replacing which is not difficult, this is especially true for headphones.

It is not always possible to determine at home without equipment whether the audio card has really failed or whether there is a problem with another device. Therefore, you should not panic right away; it is best to carry out diagnostics at a service center, and also update your computer software.

Video on the topic

If there is no sound on your computer, let's start with the simplest and most obvious actions. The lack of sound is not always a consequence of damage or failure of the sound card. Most often, the reasons are simpler and are of a software nature - for example, volume controls in the operating system are disabled or turned to minimum or problems with drivers. So, let's begin.

. Setting the Volume Controls

We check that all volume controls of the playback devices on your computer or laptop are not in the down position.
To do this, right-click on the standard volume control icon and in the menu that opens, select “Open volume mixer”, then drag all the sliders, for example, to the middle position.

After which, and From the same menu, select the item Playback devices:

From the same menu you can check the sound settings using the Check command - If the problem is resolved, you will hear a test sound from the speakers.

You can also make sound settings from the Control Panel:
Start - Control Panel - Sound

If there is no sound when playing movies, but there are sounds in Windows, most often the problem is missing codecs for video playback. To fix the problem, install a universal set of codecs.

. Checking the speaker connections (when using external acoustics)

Make sure that the power cord for external speakers, if any, is plugged into a 220 V outlet and the switch on the case is in the “On” position. In addition, external speakers often come with their own volume control, so we should make sure that this control is not set to the minimum volume.

Next, check the connector into which the plug is inserted. Typically a TRS plug is used, also known as Mini Jack 3.5 or 2.5 mm. The mating connector on the case of a laptop or desktop computer for connecting speakers is usually green or has an icon depicting headphones.
To connect a microphone, a pink or black connector is used, but then it is complemented by a microphone icon.

Checking the operation of the sound card through Device Manager

Right-click on the “This PC” icon and in the menu that opens, select Manage, then open the Device Manager section.

If the device is working normally, then to the left of it there will be no yellow exclamation mark (problem with drivers) or a down arrow (device is turned off). In this case, turning the device on and off is done through the context menu.
Often audio devices are labeled as High Definition Audio in the Audio Video Game Devices section.

Problems with sound card drivers?

Any problems with drivers or that the device is not working correctly will be indicated by a yellow exclamation mark next to this device in Device Manager.
Most often, this happens due to inappropriate drivers.
In this case, you usually need to go to the website of the device manufacturer, in our case an audio card (or for a motherboard) and download drivers that are suitable specifically for your model and installed version of the operating system.
If you have a disk with motherboard drivers at your disposal, even better! Fix the problem by installing the drivers from the disk (they correspond to the drivers from the official website), of course, if the drivers themselves are suitable for your operating system.

Pay attention to, which will automatically detect which device is installed in the system and load drivers for this device automatically. The most popular among them are, Driver Booster Free and others.

. We ask for help from the "Problem Detection Wizard"

Sometimes the Troubleshooting Wizard can help us solve problems with audio playback.
Right-click on the sound indicator in the tray near the clock, in the menu that opens, launch the wizard, as shown in the picture, through the Detect sound problems menu item.
In this case, the wizard will automatically check all possible problems in the system and offer options for eliminating them to choose from.

Good day, dear readers Denis Trishkin is in touch.

One of the main reasons why a computer does not produce any sound is that the speakers are not connected correctly. At first glance, this seems ridiculous, but believe me, this happens to everyone, even the most experienced users.

Disabled in the system( )

Another simple option, and at the same time banal, may be a general shutdown, which is set in the setup program. Just click on the corresponding tray icon and turn it on. If there is no icon, go to " Control Panel" and then into "". There you will find all the necessary items.

No driver( )

To correct the situation, we make a few simple movements:

If this does not help, you need to go to the official website of the motherboard manufacturer and download the required distribution. How to configure further?

It's simple:

Everything should work. If not, then move on.

A complete reinstallation of system files allows you to completely update all connections between hardware and software. It turns out that this procedure makes it possible to do everything as it was originally. Many people want to know how to reset sound settings? The answer is simple - install new drivers, and your problem will be solved.

The service is not working( )

Under some circumstances, it happens that the corresponding service is simply not running. To restore sound balance, you need to enable the necessary command.

For this:

Via BIOS( )

It is rare, but you can still encounter a situation when the corresponding component of the motherboard needs to be enabled in the BIOS. Again, it is worth emphasizing that this can be observed on computers and laptops, inside of which very outdated parts are installed.

To solve the problem you need:

If this does not help, most likely you have problems with the hardware. It is necessary to make a diagnosis. It is usually carried out in specialized centers.

Microphone sound( )

Sometimes situations arise when you need to adjust the microphone sound. This is usually needed in games, when using web tools for conversation, or for scoring various video files. Regardless of the goals, we perform the same actions:

Front panel sound( )

Many PC users have often seen connectors for connecting devices for audio recording and playback on the front of their system unit. Often, after connecting the appropriate equipment, nothing happens. This is because the ports need to be connected first. So how does the front panel setup work?

First you need to open the system unit and check whether the outputs are connected to the motherboard.

On some motherboards, the BIOS menu is different from others, and the item we need sounds like “ Onboard Device Configuration" Here you need to check the “”. It must have the status " Enabled" If not, we assign the necessary one.

We find in the tray the audio manager responsible for our playback device. Let's launch it. Now you need to select the item in the menu that is responsible for the front panel.

Now everything should definitely work.

HDMI audio( )

Recently, computer users have been trying to redirect video playback to their TVs. But in addition to the picture, it would also be nice to hear the corresponding audio. To do this, adjust the HDMI audio.

By and large, there is not much to do:

Everything should now work as intended.

Sometimes in the “Playback Devices” window, you need to right-click on an empty space and check the boxes next to both proposed items: “ Disabled" And "".

Well, from the article it is clear that problems with sound can be very different. I tried to describe all the possible ones that I have ever encountered. If you've seen more, be sure to describe them in the comments.

I hope the information above helps you. Subscribe and share with friends.

Quite often, users encounter the loss of sound on a computer running Windows 7. There are many reasons for this. Some are quite simple. And sometimes it takes several days to find a problem. This short review is dedicated to how to find and fix the problem.

Non-working speakers

Let's consider possible failure options:

These measures are basic, but you shouldn’t forget about them. If the check didn't yield anything, then it's time to move on.

Hardware audio settings

After obvious faults have been checked, you should pay attention to the software sound settings. It is quite possible that the sound in Windows is turned down or completely turned off. If it is reduced so much that it is barely audible, then the user will most likely assume that the computer itself has broken down.

It’s best to see visually how the sound is configured using Windows 7 as an example; on Windows 8 and 10 the operating principle is the same:

Let's look at the functions of the window that opens in more detail:

If you are unable to play the test sound, you should check to see if the sound is turned down to the minimum value or turned off altogether:

Check Device Manager

If there is no sound on a computer running Windows 7, as well as operating systems Windows 10 and other versions, you should check the status of the mini-programs (drivers) for the sound card. Most likely, they need to be updated or they are not there at all.

You can check the status of the equipment and its drivers in “ Device Manager", which is easy to find in Control panels on the " System».

Systematically displays all devices that are present on a computer or laptop, as well as the status of their drivers. If a yellow triangle is lit nearby, you should pay attention to it first. This means that the sound card is not working at all or is not working correctly. In our case, we are interested in the item “ Sound, video and gaming devices».

If a problem is identified due to which the sound does not work, you need to download and install a driver that is compatible with this PC. The current state of your computer can be maintained using special utilities for automatic updating and searching for the latest version of drivers for any equipment on a PC or laptop. For example, the program Everest will determine the sound card model, check all drivers for relevance and tell you where to find the necessary drivers for sound on Windows 7.

When you monitor the current state of your computer and carry out regular updates, you may encounter the problem of no sound during the next automatic driver update. The source of the problem may be an updated driver. "" will help restore the working situation. On the " Driver» of your sound card, you must click the Rollback button.

If the problem disappears, it is better to disable automatic driver updates for this device.

Updating drivers in Windows 10

The algorithm of actions consists of the following steps:

If the Internet is connected, then in the browser search engine you need to type a search query like: (Your_laptop_model) support or (Your_motherboard_model) support.
In the support section, select your computer model and click Select.
From the Driver-Audio line, select to download to your computer the entire set of drivers that are in this list.
If you are prompted to download drivers for Windows 7 or 8, and not for Windows 10, it’s okay, at least it’s better than nothing. The main thing is that the bit depth of the operating system does not differ from the installed one (x64 or x86). The driver that is missing in the system is included in the package offered by the official website.
After the drivers are downloaded, you need to install the entire kit. If the system requires you to enable compatibility mode with previous versions of Windows, this must be done.
After this, check whether the sound appears or not.

No codecs for audio/video

If there is sound in the browsers, but there is no sound when you start the video on the PC, then you should look for the problem either in the media player itself or in the audio codecs.

To constantly watch videos, it is recommended to use KMR player. He has already proven himself and is showing good results. The creators of the program have provided a lot of different codecs for video playback. And, as a rule, most films are successfully reproduced in this program.

The problem with codecs can be radically solved using the package K-Lite Codec Pack. It can solve the missing sound problem. It has a full set of current codecs that open almost all popular formats, both video and audio files.

Viruses and adware

Problems with sound on Windows 7 may mean that a virus has appeared in the system. There are many types of viruses and they can negatively affect the operating system.

How to behave if the sound on your computer disappears and you suspect a virus:

Take a close look at how your computer works as a whole. If it begins to freeze frequently or suddenly slow down, then most likely the PC has been subjected to a virus attack. If the installed antivirus program failed and missed the virus attack, then it is best to check the system with a third-party antivirus with up-to-date virus databases. For example, you can use the utility Dr.Web CureIt. This healing utility successfully cures an infected system.
You can try checking your computer using Live CD(emergency boot disk). With its help, you can download a lightweight version of the operating system with a ready-made antivirus. If you boot the restored system from Live CD sound appears, then most likely there is a malfunction in Windows 10 itself. Most often, you will have to reinstall it or perform a system restore using restore points, if this mode was enabled and restore points were created.

Checking the BIOS settings

If your computer or laptop has a built-in sound card and there is no sound even in headphones, then you can look BIOS.

This is an extreme measure - AC97 is enabled by default in the factory settings. If the settings are lost, the sound device in the Windows operating system will not work.

Each computer logs into the BIOS differently. For example, for ACER computers, before booting the system, you must press and hold the Del key. In general, before loading the operating system, you must indicate how to enter the BIOS.

After pressing the Del key, the following dialog box will open, in which you need to select the item “ BIOS Setup».

In the window that opens, you need to find an inscription like AC 97 Audio, use the arrows on the keyboard to highlight this inscription and click on the Enter key. A dialog box will appear to select which function to activate HD Audio or AC97. We are interested in the AC97 “Auto” inscription. Confirm your choice and use the ESC key to exit this section. Exit the BIOS, saving the settings.

If you can’t get the sound back after changing the BIOS settings, then the last option is to replace or send the sound card for repair.

Laptop owners often encounter the problem of no sound in the Windows system. Due to frequent overheating of the sound chipset, the computer begins to malfunction. And all the other electronic components simply suffocate with dust, unless, of course, you do regular cleaning, and gradually fail, which can also lead to loss of sound on the laptop.

Conclusion

Of course, these are not all the reasons why there may be no sound, but the main, most common versions are revealed.

So, we told you how to restore sound in Windows 10, 7 and 8. And our main advice is not to despair, but to try all the options step by step.
