Speakers with two input sources

Ok, what I'm trying to do is use my 5.1 speaker set for both my computer AND Playstation 3. Preferably with 5.1 support on the latter.


Problem: Only room for one set of speakers, and said speakers need to connect to the HTPC and A/V Reciever.


Reciever is a Technics SA-G90. It's fairly old, so I can't just go from the sound card to the reciever via digital coax-to-3.35mm plug.

Well, I could, but then I would not have surround sound.


My HTPC speaker setup is the sub/amp from a Logitech Z-5300. It requires RCA connections with any satelite speakers.

I took the speakers from my SA-G90 and made a little RCA plug adaptor for each speaker. (These speakers are much better than the tiny Logitech satelites that originally came with the Z-5300)


The SA-G90 reciever only accepts speaker connections via Speaker Wire (not RCA plugs like the Logitech sub/amp box from the Z-5300).


So, how could I connect both the reciever and the Logitech Z-5300 sub/amp box with the same speakers and still beable to have 5.1 surround sound from both the HTPC and the Playstation 3 (or any other console, or whatever connected to the reciever)?


I assume it would not be safe to just make a split in the speaker wire going to the Logitech box to connect the reciever? I really don't want to have to unwire one or the other every time I want to use the opposite device.



PS - currently using an RCA to 3.35mm plug to connect the PS3 to the Line-In on the sound card, but this REALLY sounds horrible, like the bitrate is 32 kbit
