Hi guys, Hoping someone can help me out here. I have a PC which I've been able to hook the video up to my TV using a VGA cable. Now I need to sort out the sound. I have a cable which is a 3.5mm prong (like what headphones would have) on one end and on the other end it has the Red & White RCA prongs. I've tried plugging the 3.5mm end into the "Audio Out" on the PC and RCA ends into my receiver but I don't get the surround sound. Currently I can only get the sound to come out of one front speaker AND the sub. The audio signal isn't splitting using this cable. It's only staying on the White RCA prong. Is there something else I need to do? If it helps the receiver I have is a Sony 110W X 6 - Model # STR-DG500. No clue how to tell what audio/video card the computer has so if that info. is required can you tell me how I look it up. Thanks.
