1. First attempt to install the latest drivers for your sound card and hopefully revive it.
2. If that doesn't work, install a new sound card. And if it's got an integrated sound device, disable the integrate device before installing the new one.
Hope this helps.
The sound totally and suddenly completely went off/out on my Compaq Presario 5000 running XP.Never happened before on this older rig.Volume settings are normal(varying them has no effect).System Restore and reboots ineffective on problem. Virus/malware/spyware shows no threat.Any suggestions to fix this problem short of buying a new pc! would be really appreciated asap!
