I am looking for a receiver that can switch between two different 5.1 speaker outputs, or maybe a 5.1 and a 4.1. Simultaneous play from the same or different inputs is not necessary. Even high end computer speakers suck compared to a moderate home theater setup, so I want to use a decent receiver and speakers for the computer. I currently do not have a 5.1 receiver for my TV, so I need one of those as well. Rather than buy two, I am trying to find one that can do double duty. All the receivers I have seen so far can only switch two front speakers, not the whole setup.
