I daisy chained my systems sound from their output to the next systems aux in till they all got to my main box that went to my sound system. Worked great for non wow stuff. Could hear sounds from any system, videos etc. But playing wow... Uhgg that was a nightmare even just having one guy hit a mining node sent 5x pick ax noises out of the speakers. AOE mass killing spells going off death crys etc 5x over.... The ears, they bleed.
