To start this off, my setup is mostly cobbled together with spare stuff I had laying around the house. Right now I have a HP w1707 for my primary display via VGA, and a small 720p TV as my secondary display via HDMI. Right now I'm trying to get 5.1 audio from my graphics card, to my secondary display, and then to my A/V reciever via Digital Coaxial (my reciever doesn't support HDMI in) yet I can't seem to get 5.1 audio, or even send a signal from the source. I've tried messing with Realtek drivers, AMD Catalyst; everything. If anyone has a solution for me, I'd be happy to hear it.
EDIT: I downloaded the ATI HDMI driver from Realtek, which only disabled my display as a device, and now shows up as "Not plugged in" in the Windows sound panel, even though it is.
