Have you tried to locate the Sound Driver for your computer on the Internet?
First right click your speaker Icon and open Volume control
and make sure your sound is not muted. Located on your lower right.
If you don't have a speaker Icon go to the Control Panel and check your sound.
Next
Windows XP
See if your sound has been stopped in Services Under
Windows Audio.
Start - Control Panel - Open Administrative Tools - Open Component Services - Click Services (Local) and Scrowl down the list to Windows Audio to see if it says - Started. If stopped
Left click Windows Audio and click restart. -
Or
Right click Windows Audio - left click Properties - Left click Start

If still no sound next try this But be careful because your in the Registry and you can harm your computer.
Go to Start>Run, type in regedit and hit ok.
Navagate to HKEY_CURRENT_USER\Control Panel\Sound
"Beep" and "ExtendedSounds" should both be set to "yes" in order for the speakers to work.
If you still don't have any sound.
If the above doesn't work, go to control panel and open System Icon -
Hardware Tab - Device Manager - Click the + Plus sign for Sounds.......... -
Right click Realtek AC 97 (or whatever sound you have)- Left click - Update Driver.
To update you will need the CD that came with your computer.
For Windows XP but check anyway.
Maybe some of this will help or maybe not.
That's all I have on Sound.
