[HDA-Intel - HDA NVidia] sound card recognized by alsa but not loaded by PulseAudio [10de:07fc]

[Mathieu Trudel-Lapierre]

My sound card is properly seen by alsa (apparently) but not listed at all by pulseaudio.

I can successfully play sound through VLC if I reset the sink to use alsa via that sound card's Front Speakers.

Adding 'regression-release' since this was working perfectly with pulseaudio in Oneiric. I also do believe it was working earlier with Precise, though I've been slow to report this particular issue.

Please add a pulse log: https://wiki.ubuntu.com/PulseAudio/Log

The problem actually appears simple now: lightdm's pulseaudio process should get killed off once the user session is opened:

mtrudel@selene ~ % ps -ef | grep pulse
