Annoying buzzing in Audio on Proc. load

Whenever the processor, or maybe it's the hard drive, is under load, the audio gets this tiny static noise. I had it once on this 1ghz AMD, but now it's on my 2.8C Asus P4P800-VM. What's up with that?

Do your speaker wires run past alot ofpower cables? It could be EMI.

Onboard sound runs through the south bridge. As does the PCI bus (which is what the hard drives use). I have never heard of this problem on a P4P800, but on nforce2 boards the problem is solved by cooling the south bridge.

So basically put a small heatsink on your south bridge and see if it helps.
