Which jack you fed the PC audio to. I find that many don't have it cabled proper.
I'm having a bit trouble when I'm trying to connect my PC to the TV.
I have a Nvidia GeForce 9400 GT and creative SB0460 X-Fi sound card, and would like to use the TV speakers as a default speakers but no matter what I do it doesn't seem to work..
I would really appreciate your help!.
