No sound signal on Windows XP computer

Software and hardware are responsible for sound and playback of audio files on a computer with Windows XP - 10. It is because of their correct functioning and interaction that it becomes possible to watch movies, listen to music, play games, process audio data. But when one of these components is missing or it works in an abnormal mode, the whole chain is broken and, as a rule, the sound disappears on the computer. Today we will consider what to do if sound disappears on Windows and how to determine the cause of the problem.

Components responsible for audio playback

Audio processing hardware includes:

sound or audio card. It can be either integrated into the motherboard (in most cases) or discrete (the expansion board is connected to the PC separately). A sound card is a chipset with its own controller, chipset, and several ports for connecting devices.
external devices for playing sound. These include speakers, speakers, 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 operation of sound, sound card and its interaction with the operating system;
Audio Windows service - allows you to play sound for applications and the Windows operating system from XP to 10;
audio codecs - 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, decoding it and transferring it to the application for playback. If it is not there, there is no sound on the computer either.
sound control software - as a rule, such products come with drivers. With their help, you can adjust the volume, equalizer and the imposition of audio effects on audio in Windows XP - 10.

Reasons for signal disappearance

Based on the above, the answers to the question "Why did the sound disappear on a computer with Windows XP?" there may be many. These are both hardware problems and misconfiguration of software components. If the sound disappeared after reinstalling the operating system - the reasons are the same, when the audio is not in the films - completely different. Next, we will consider the possible factors for the disappearance of sound on the computer.

Possible reasons why many users lost sound on Windows 10:

Audio equipment is disconnected or incorrectly connected.
Audio codecs and / or sound card drivers are missing.
Windows Audio service was removed from startup or did not start.
Incorrect system setup: sound disabled in BIOS or Task Manager , more precisely, and audio cards.
Damage or modification of Windows 10 system files, for example, by a virus.
Changed the volume setting in the system to zero.
Incorrect application setting (wrong sound card selected if there are two).

Checking hardware components

Make sure the audio playback devices are properly connected.

The cable from speakers, headphones or a speaker system must be connected to the green connector on the back of the cabinet. Perhaps you inadvertently plugged the jack into the wrong connector, so the sound disappeared. When using the front panel output on your computer, you need to make sure it is connected to the motherboard.

Then the sound level is adjusted.

Perhaps the volume of speakers or sound in a system with Windows 10 is set to zero, or the acoustics are not connected to the network.

Reboot the PC and press Del or F2 to enter the BIOS settings. Using the cursor block of the keyboard, go to "Advanced" and find the item "Audio Controller". Its value must be "Enabled".

Solving software problems

There are much more factors related to the problems of the software shell that caused the disappearance of audio on a PC with Windows 10, and we will consider them.

Drivers

We go to the "Task Manager" through the context menu "My Computer".
Expand "Sound, video, game devices" and check for the presence of the audio driver and the activity of the sound card.

If not, download the installation package from the manufacturer's official website and install the driver, or call the context menu of the unknown equipment, go to the "Information" tab.

Select "Instance Code" and copy its buffer.

We go to the devid.info website and paste the contents of the buffer into the search bar.

Download the latest driver and unpack the archive.
We call the context menu of the unknown device, click "Update" and specify the path to the contents of the downloaded archive.

Driver crash

If a sound icon with an exclamation mark is displayed in the taskbar, then you need to configure or reinstall its driver. We go to the properties of the audio card in the "Task Manager" and remove the driver. After restarting Windows 10, it will be installed automatically, if not, we will install it manually.

Launch Windows Audio

We enter "services.msc" in the search for XP or 10s, and in the window that appears, we find the Windows Audio service. In the properties, you can configure it: select "Automatic" start and start the service manually if it is not active.

Codecs

Your PC may not have an audio codec. Download the latest version of the codec, it is recommended to use the K-Lite Codec Pack, and install it on your computer. After restarting the 10-ki, the sound that disappeared should appear.
