I have a sapphire 6850 in the computer i built and when i first turned it on the sound was coming through my monitor speakers via HDMI cable. I was able to change this so it came through the audio jacks on my mobo with no problem, but now, i have my computer connected to a 32" TV via HDMI and i can't seem to figure out how to make the audio go back to HDMI and play through my TB. The only device listed in "playback devices" is the Realtek digital output, and from what i've read on other forums it should have a "HDMI" selection, which isnt there. Any ideas?
