Rzyard, my noise was exactly what you described. Mac said flat out it's the PC. I spent time checking every audio cable and all the connectors, unplugging the mixer, using headphones alone, using process of elimination, all that stuff. It's the PC. Just find a two prong adapter, follow his instructions and be done with it. If you're really paranoid buy that $75 thingy that truly eliminates the shock potential.
