I want to start running Boxee or something similar. I have a DVI output (from comp) to an HDMI input (on tv).
However, I dont know what to do about sound, since audio is ran from my DirecTV box to my surround sound. I have a PC Express or newer video card.
If it's a recent ATI card, it has a built-in audio chip that you can switch the output over to. If its a recent NVIDIA card, it has a tiny white digital audio input connector on the top, which is supposed to connect to the internal digital audio output header on the motherbaord.
