I think this thread can go here. I'm trying to hook my pc's 5.1 to an older Sony receiver. The Sony has an older rca connectors. I'm wondering if there are cords I could use to connect them. The 5.1 on the pc is from an Asus M4A88TD-M.
The main problem is PC Audio (AC97) carries TWO signals per jack, instead of the one RCA carries. Aside from that, its the same exact signal. (IE: The "Green" PC audio jack is equivalent to the Red+White RCA jacks).
As such, you can just split the PC output into two for each PC output, and connect to the receiver that way.
