Title:
  Wrong or no soundcard in Pulseaudio

Status in Ubuntu Studio:
  Won't Fix

Bug description:
  I am running 10.10 on an Intel Core 2 Duo.

  Right now Pulseaudio only shows null outputs.

  A few days ago, it would have shown the CA0106 (X-Fi Extreme Audio) on
  a good day. That is, when I reboot my computer enough times that
  pulseaudio detects it. Most of the time it would only detect my
  STAC9227 soundcard. Rebooting the computer once or twice would make it
  detect the CA0106 instead. I thought it might be the snd_hda_intel
  drivers causing problems, so I disabled it through the BIOS after I
  found a page showing me how to blacklist those drivers. Now pulseaudio
  detects no soundcards and only shows Null output.

  Here is the output of various commands:

  $ pulseaudio -vvvv

  running "fuser /dev/snd/" doesn't help.

  Also possibly of interest:

  1: my microphone wouldn't work even if the output was working.

  2: My client.conf file in my home folder has one line: "autospawn = yes"
  If this is set to "no", the pulseaudio server will fail to connect. If I quickly turn it back with Gedit and start pulse again with paman, it will succeed.

  The purported fixes on forums use asoundconf or alsa-utils, but
  neither of these are installed!
