Pretty new to HDMI audio on these cards,
I'm trying to install the 4350 into a vista ult. 32bit htpc. The video works fine over HDMI to my Denon avr-789. The audio isn't passthrough on those HDMI channels.
-I've disabled the onboard audio
-cleaned all old nvidia and ati drivers off with drive sweeper
-installed ati drivers 3.12
-installed realtek ATI HDMI AUDIO driver 2.39
And about 10 variations with older drivers, different order, everything.... and I cannot get the HDMI device to show up under the audio output device's. As you can see in the attached picture ATI HDMI audio appears under sound controllers after I install 3.12.... but then the realtek drivers seem to do absolutely nothing.
I attached a picture so it would be more clear.
Are there any other requirements for HDMI audio to work hardware wise? My mainboard/proc are a bit older but I can't see that affecting an audio chipset on a video card.
My Auzen x-fi meridian was completely fine, sound has never been an issue before...
I could really use some suggestions at this point!! I've read old posts for a few hours but it seems pretty straight forward at this point... but I'm sure I'm missing something small.
