I never thought that there could be so many problems with sound! It is indisputable, but it is a fact. quite a large number of laptop users are faced with the fact that at one point, the sound on their device disappears.
This can happen for various reasons and, most often, the problem can be fixed independently by rummaging through the Windows settings and drivers (thanks to which, to save on computer services). In this article, I have collected some of the most common reasons why sound on laptops disappears (even a novice PC user can check and fix it!). So…
Reason # 1: adjust the volume in Windows
Of course, I understand that many can express dissatisfaction. “what is it really."For such an article. But still, 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) with the right mouse button, several additional options will appear (see Fig. 2).
I recommend opening the following in turn:
- volume mixer: it allows you to set your volume in each application (for example, if you do not need sound in the browser, then you can turn it off there);
- playback devices: in this tab, you can choose through which speakers or speakers to play sound (and indeed, in this tab all audio devices connected to the device are shown. over, sometimes even those that you don’t have! And you can imagine, on non-existent devices sound is made.).

In the volume mixer, pay attention to whether the sound is minimized in your running application. It is recommended to raise all the sliders up, at least for the period of searching for the causes and troubleshooting the sound (see Fig. 3).

In the “Playback devices” tab, note that you can have several devices (I have only one device in Fig. 4). and if the sound is “delivered” to the wrong device, this may cause the sound to disappear. I recommend that you check all the devices displayed in this tab!

By the way, sometimes the Windows built-in wizard helps to figure out and find the causes of sound problems. To start it, simply right-click on the sound icon in Windows (next to the clock) and run the corresponding wizard (as in Figure 5).

Reason # 2: drivers and their settings
One of the most common causes of problems with sound (and not only with it) is conflicting drivers (or lack thereof). To check their availability, I recommend opening the device manager: to do this, go to the Windows control panel, then switch the display to large icons and launch this manager (see Fig. 6).
Fig. 6. Launch device manager.
Next, open the tab "Sound, gaming and video devices." Pay attention to all the lines: there should not be any exclamation points or red crosses (which mean that there are problems with the drivers).

By the way, I also recommend opening the "Unknown devices" tab (if any). It is possible that you simply do not have the right drivers in the system.
Fig. 8. Device Manager. an example of a problem with the driver.
By the way, I also recommend checking the drivers in the Driver Booster utility (there is both a free and a paid version, they differ in speed). The utility quickly and easily helps to check and find the necessary drivers (an example is shown in the screenshot below). What’s convenient is that you don’t need to search the various software sites yourself, the utility will compare the dates and find the driver you need, you just have to click the button and agree to install it.

Reason # 3: the sound manager is not configured
In addition to the sound settings in Windows itself, there is (almost always) a sound manager in the system, which is installed along with the drivers (in most cases, it’s Realtek High Definition Audio) And quite often, it is in it that not optimal settings can be set that make the sound inaudible.
Very simple: go to the Windows control panel, and then go to the "Hardware and Sound" tab. Next, this tab should see the manager that is installed on your equipment. For example, on the laptop that I am currently setting up. the Dell Audio application is installed. This software also needs to be opened (see. Fig. 10).
Fig. 10. Equipment and sound.
Next, pay attention to the basic sound settings: first of all, check the volume and the checkmarks, which can completely turn off the sound (see. Fig. 11).

Another important point: you need to check whether the laptop correctly detects the device connected to it. For example, you inserted headphones, but the laptop did not recognize them and does not work properly with them. Result: there is no sound in the headphones!
To prevent this. when connecting the same headphones (for example), the laptop usually asks if it has correctly identified them. Your task: to tell him the sound device (which you connected) correctly. Actually, this is what happens in Fig. 12.

Reason number 4: the sound card in the BIOS is disabled
On some laptops, you can disable the sound card in the BIOS settings. Thus, you are unlikely to hear a sound from your mobile "friend." Sometimes BIOS settings can be “accidentally” changed by inept actions (for example, when installing Windows, inexperienced users often change not only what they need.).
Actions in order:
1. First go to the BIOS (as a rule, you need to press the Del or F2 button immediately after turning on the laptop) You can learn more about which buttons to click in this article: https://pcpro100.info/kak-voyti-v-bios-klavishi-vhoda/
2. Since the settings in the BIOS differ depending on the manufacturer, it is quite difficult to give universal instructions. I recommend that you go to all the tabs and check all the items in which the word "Audio" is present. For example, on Asus laptops there is an Advanced tab in which you need to set the High Definition Audio line to Enabled (i.e. enabled) (see Figure 13).

3. Next, save the settings (most often the F10 button) and exit Bios (Esc button). After rebooting the laptop. the sound should appear if the reason was the settings in Bios.
Reason # 5: lack of some audio and video codecs
Quite often, the problem is observed when trying to play some movie or audio recording. If there is no sound when opening video files or music (but there is sound in other applications). the problem is 99.9% related to codecs!
I recommend doing this:
- first remove all old codecs from the system completely;
- then restart the laptop;
- reinstall one of the sets offered below (find the link) in the full advanced mode (thus, you will have all the most necessary codecs in the system).
For those who do not want to install new codecs in the system. there is another option, download and install a video player, which already contains everything you need to play files of various types. Such players are becoming quite popular, especially recently (and it is not surprising who wants to suffer with codecs ?!). You will find a link to an article about such a player below.
Reason # 6: a problem with the sound card
The last thing I wanted to dwell on in this article was the problems with the sound card (it can fail during sudden surges in electricity (for example, during lightning or welding)).
