I have just recently purchased an A/V Receiver-Sony STRDH520, a low-end 7.1ch receiver. I also have a myriad of various speakers to use, from Klipschs to Polk Audio speakers to Bose 301s. I also just purchased a Polk audio 12" powered sub to go with these. Anyway, I plan on only using 5.1 right now. The problem is that I plan to use it as the sound system for my PC, but I cannot locate anything on the internet that is relevant. It's as if no one else has ever done this. Am I somehow very confused? Even the Sony Support website has nothing at all to mention about this, making me feel that I am entering some unmarked territory. ONce the subwoofer cable and the set of RCAs come in, I was hoping to get a suggestion or two on how to connect this. I have a SPDIF cable and an output via the onboard sound, as well as HDMI outs and the monitor is also HDMI capable. I bought this receiver because it had just about every type of connection I would need. hehehe, and I guess that's my problem, 'cause I don't have a clue as to which ones to use. Thanks for any help, or even for telling me why I'm completely out of my gourd for doing things this way.
