Short and sweet: I need an audio selector that switches between two 7.1 channel analog inputs (8 RCA jacks per input). The rear of my Pioneer receiver has one set of 7.1 channel analog inputs consisting of 8 labeled RCA jacks. The sound cards on my two home theater PCs are connected to the Pioneer via digital optical cable. However, I strongly prefer multi-channel analog input for music and games. The HTPCs' sound cards support 7.1 channel analog output over stereo RCA cables: - Auzentech XFi Prelude over 4 generic minijack-to-RCA stereo cables. - SB Audigy 2 ZS over Creative brand RCA cables. I want to switch the inputs to the Pioneer between the XFi and the Audigy. I'm willing to walk over the switch and press a button, since I won't be switching often. I'm even willing to buy four two-way selectors, but I'd really like to avoid the clutter. Posted in this forum rather than HTPC since the core issue is how to switch 7.1 analog audio signals from two devices. I could be talking about two very old DVD players instead of two HTPCs. Help appreciated!
