if you look at those bug reports of no sound for those on-board ac97 codecs
with ubuntu 12.04
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1033996
how does pulseaudio determine which controls are effective in the headphone
path and speaker path of those ac97 codecs ?
the analog-output-stereo profile for the line out jack is missing
( 0.056| 0.000) D: [pulseaudio] alsa-mixer.c: Removing path 'analog-output'
as it is a subset of 'analog-output-headphone
is there any solution for those snd-intel8x0 and those onboard ac97 codecs
with headphone playback volume control ( no ctljack control and no phantom
port)?
