pulseaudio mess

[michael caron couturier]

Whatever I try, my motherboard sound card work with gnome-orca until
my user acount is fully loaded and stop there, pavucontrol only see a
dummy, my gpu sound probably work as it should.

Could you help me with this crap ? I'm clueless now, I checked almost
anything I could have tried ...

/etc/modprobe.d/alsa-base.conf :

options snd-hda-intel model=1
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
