Thank you very much for this really important hint. As I said in my first
message I wanted to be able toreduce the number of cables on my desk. 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 ?
It also has a problem controlling the device:
Working onboard:
audioctl show-control -d /dev/sound/audiohd:0ctl
CONTROL VALUE
volume 75
front 75:75
headphones 75:75
speaker 75:75
mic 50:50
line-in 50:50
beep 75
monitor-gain 100:100
record-source mic
Non-working HDMI:
audioctl show-control -d /dev/sound/audiohd:1ctl
CONTROL VALUE
volume 100
Bad enum index 10 for control 'record-source'
