HTPC woes

I installed an ATI HD4350 video card in my htpc last night; and around 2am I had given up on trying to get 5.1 outta it. I’m pretty sure the software config is the only real problem because the EDID is detected properly; and the old sound card had some kind of layer in place to matrix audio automatically.

I’m hoping this didn’t turn out to be a waste of money and time. Tonight I’m going to reinstall the operating system and start fresh.
