I'm recording staight out of the back of my amp, line out to line in on the card. It is interesting to note that I don't seem to have this problem when I record at a lower recording hrz like 84/24bit, only at 24/96. bypassing the amp has no effect and muting the source doesn't help because the distorted sound gets recorded right on to the track. Also, I can copy files off of loop discs and they play no problem, only when I try to record line in does this problem occur I have a 2.8 Ghz AMD processor so I don't think that is the problem
