Last night while listening to internet radio I lost the sound. Not entirely as it's now alot quieter.

I'm running a MSI KT3 Ultra2 mobo with onboard sound. I've tried restoring a ghost image of my XP Pro system, uninstalling the sound drivers and reinstalling, and checked the wires going to my stereo. And ran the wires to a different input on the stereo. Same quiet sound problem.

This mobo is about 2½ months old. I've checked it for leaking capacitors and don't see any.

Any suggestions? TIA
