But now I have discovered a more pragmatic reason: All new videocards do not have VGA ports so most people have to use an HDMI cable. Now suppose I do not want to usethe nVidia audio processor, how can I still use the onboard audio processor? In my case, there is no sound when I use an HDMI cable. In different words, HDMI means no sound. Question: Has anybody successfully usedHDMI and the onboard audio? Maybe my hardware is completely problematic.

Just tried with my setup (oi151a9 with NVidia Quadro 2000 HDMI
to DELL U3017 Monitor, audio output to boxen) : The device is there
(/dev/sound/1), 'audioplay -v 100 -d /dev/sound/1 
/usr/share/sounds/freedesktop/stereo/goksound2.wav' works, but : absolute SILENCE .

No twiddling with the (only one) volume control for that device and
Monitor controls helps.

So I would conclude that this is currently not properly implemented.
Or are there missing options for a proper Xorg.conf that must be
enabled ?
