One of the most common issues experienced in computers is "no sound"
problem. The issue can be due to incorrect volume settings, cable
connections not connected properly or corrupted audio drivers.
Steps:
1.Adjust the sound settings
*.You will find a Sound icon in the task bar, right click on it and
select ¡°Adjust Audio Properties¡± and ensure that the checkbox beside
Mute is unchecked. If this box is checked, uncheck it and click on
Advanced and move the sliders so that all the Settings are set to their
maximum.
*.In windows vista and Windows 7, we have Volume Mixer. Make sure that mute is not enabled and slider is at is maximum position.
*.If the audio icon is missing from the task bar, click on Start menu and select Control Panel.
*.If you are Classic View, double click on ¡°Sounds and Audio devices¡±
and select the checkbox beside Place Volume icon in the taskbar and
click on OK.
2.Test with different audio applications such as Real Player or VLC player.
3.Install Audio Codecs
*.You may face sound problems when the required codecs are missing,
therefore I recommend you to install audio codecs that are required for
your windows.
4.Visit the link:

5.Try System Restore.
*.If the issue persists after adjusting the audio settings then perform System Restore
*.In windows xp, Click on Start menu and select All Programs
*.Click on Accessories and System Tools, select System Restore to open it.
*.In windows 7 and Vista, click on Start button and just type system restore in Search.
*.Select System Restore from the results.
*.Follow the System Restore wizard by selecting the first option ¡°Restore my computer to an earlier time¡±.
6.After you have restored your notebook to a previous time, check the sound in the notebook.
7.If restoring the System will not fix the issue, try the following steps:
*.Windows Audio Service
*.Check with the audio service i.e Windows Audio Service,
*.Hold Windows Key and R simultaneously which will open Run window.
*.Enter services.msc and click on OK.
*.If the operating system is Vista enter services.msc in the Start Search and double click on services.msc from the results.
*.The services window opens, move down to Windows Audio service, check
if the Startup Type is Automatic and if not, change it to Automatic.
8.Right click on the Windows Audio and choose Properties and in the

service and click on OK.
