I have studio at home using a Imac desktop, Adobe audition 5.5 and M audio fast track pro. I getting a hiss from what I perceive to be the M audio but I have been reading reviews on other mixers and hear the same issue. Is there some sort of "grounding" issue for the USB? Is there a fix for this. I have contacted AVID who makes the M audio and they seem to think its a "hardware issue with the M audio. I will have to purchase another mixer before I ship the M audio off for repair so If I have the same issue with another mixer that may tell me what I need to know.
