It sounds like what you're experiencing is a ground loop. Make sure that
everything in your computer system and your audio chain (interface, mixer,
etc.) is using the same A.C. electrical circuit ... use one or more power
bars if needed and have them all going to one plug-in at the end.

Alternatively, if the M-Audio interface or any of your other audio equipment
has a ground lift switch, lift the ground to see if that solves the problem.
