I also need help with this. For the last year or so the sound on my comp has been all staticy and annoying like a blown amp. I thought it was the speakers but it also does it when I have headphones on aswell. Everytime I try to listen to music it's difficult because the sounds is all wierd. I don't think it's the sound alltogether. It's just when I move the nob to the volume on the speaker it makes it. It especially does it when I click the thing up from mute to on.
