I'm trying to find a soundcard that has dual optical input (call it SPDIF or TOSLINK if you like). I've got my PC, 360, and PS3 all hooked up to the same monitor, and I can switch between video sources just fine, but for audio right now, both the 360 or PS3 go through the crappy built-in speakers, instead of through my surround system, since I don't have any optical inputs. Is there a card out there that will let me do what I want? I imagine it will also have to be pass through, as I read this on some cards that have just one, but I don't know how all that quite works.
