If the sound is onboard [built into the motherboard] then it's entirely
possible that svchost is taking all of the CPU cycles causing the no
sound issue.
Download the Windows Update Agent for the version of XP installed,
either 32 (x86) or 64 (x64)bit and save it.
Then download KB928791, either 32 (x86) or 64 bit (x64) and save it:
http://support.microsoft.com/kb/927891/

When the downloads complete install the Windows Update Agent first, then
install KB927891, and restart the system.
Did that resolve the issue ?
