dmesg you've provided is not verbose and so quite useless for HDA
diagnosing. From what I can see here, it looks more alike to older
GeForce 8300 based board (ASUS M4N78 PRO) I have, then to newer cards.
Unluckily, I've tried all I could from the HDA side and still unable to
make HDMI audio work on that my board. So either it is X11 video driver
problem not initializing audio path properly on this chip, or I am
missing some chip-specific clues.
