I can not get audio over HDMI to work. Speakers or headphones work great. After 16 hours of futile research, here I am.
I have an I3-2105 on an ASRock Z68M-ITX/HT board and a hauppage capture card. Running 11.10 with kernel 3.1 (the default kernel got no HDMI sound either)
Other than and updated kernel I have changed the xorg.conf to provide a custom resolution to a Vizio VW32L tv.
Nothing is muted in aslamixer. I noticed that the Monitor Identifier in xorg.conf is HDMI3 and xrandr shows that HDMI device connected. But, the audio devices are HDMI0 AND HDMI1. Where is the one for the physical HDMI3 connection? I guess my main question is how can I map the audio HDMI outs to montior HDMI outs and am i missing an audio device?
