Does anyone know of a switch that will allow me to connect 2 sets of 5.1 PC speakers to 1 computer? Ideally it would be able to switch between speakers A, B, or both A & B - just like a stereo. I have an older set of 5.1 PC speakers that I'd like to hook up on my deck by the pool so I can listen to Music Match out there as well! I've done a bit of searching on the internet but all I can find is pretty much just the opposite (KVM switch to use 1 keyboard, mouse, monitor, & speakers with 2 computers). TIA!
