I have a HTPC using a radeon 6870. Everything works perfectly fine, with the amd hdmi audio device being the default playback device. However, sometimes I want to listen to music through my theater speakers but do not need my television on. Only problem is, that as soon as I shut off the television, the ati hdmi audio device goes offline? I've tried the newest CCC drivers and still no luck.
And just to clarify, it's a win7 32bit install and I have a hdmi cable going from radeon to my denon AVR, and from the AVR to the television. I am really stumped and have absolutely no idea how the television plays any part in the audio going to the receiver.
