I've plugged my Home Theatre PC back into my TV using as always, a DVI-HDMI adapter on my dedicated 3650 passive graphics card and then obviously a HDMI lead from the adapter to the TV. The sound on the computer isn't plugged in(which is what I used before as my tv never ran sound unless using PC Input(VGA) and the 3.5m audio jack port(
Another way of getting sound was to use onboard graphics card HDMI-HDMI(the mobo has HDMI built in)).


However, somehow the sound is working through the tv? :S That must mean the sound is going through the graphics card and out the DVI port? I didn't think that was possible. I'm not complaining mind :)
