Dear Kenneth
the standard kernel on 12.04 is 3.2 and I had unconfirmed info that with
this kernel there is no HDMI audio support. As shown in my mail from
yesterday I added Kernel 3.6.6 and this obviously is supportive of HDMI.
Whether this would be the case in your situation, I cannot judge since
the NVidia cards have some specialities with respect to HDMI audio.
