Alright. I didn't know if the "coaxial" RCA was any different. I've got the receiver hooked up to the computer now through a 3.5mm to RCA line. I can't get hardly any sound out of the right speaker, and when I do (I can only get it on "mono movie" setting) it's faint and is slightly behind the other speaker. It's not the speaker itself, I tested it on the working side and it was fine. I may try the coax to see if there's any difference.
