Not included sound

Sometimes the reason for the lack of sound is not a problem, and the fact that the elementary sound off, and we all wonder why my sound does not work?

In the computer under the operating system Windows sound control is:

  1. on the audio device;
  2. in Windows system settings;
  3. in the settings utility driver-sound card;
  4. in the settings of specific programs.

Windows 7

«Seven» as opposed to XP has a built-in tool to automatically diagnose and correct system problems, including with sound. This feature runs automatically but can be run manually directly from the window where the problem occurred by pressing the corresponding button.

Using a registry operating system, you can make the most of fine tuning the system. But the changes to the registry can lead to the reassignment of the sockets of the sound card that will lead to a lack of sound.

To fix this problem is possible by changing the binary value of the pin01, which is responsible for the rear green Jack to be used for audio output.

To do this:

  1. open the registry by typing the menu «run» command «regedit»;

The jumpers on the motherboard

Some, especially older motherboards there are jumpers that switch the sound output from the front panel to the rear and Vice versa. If the jumper is wrong may not be sound.

Unidentified audio codecs

In some cases, the problem with sound is essentially a problem of playback of audio files of a particular type codecs which do not exist in the system. It is therefore recommended to test the sound files in the format wma or wav. The codecs for these formats are included in the basic version of any operating system.

To play the sound of other audio formats you need to download a codec package such as K-lite or install player uses its own codecs, for example GOM or VLC.

Front panel

The reason for the lack of sound on the front panel can be:

  • incorrect jumper on the motherboard;
  • no connect the front panel to the motherboard.
