Title:
  Sound works on LiveCD, but not after install

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Fix Released
Status in “mythbuntu-meta” package in Ubuntu:
  Fix Released

Bug description:
  Motherboard: Intel DG965WH

  I had a previous 9.04 install (had been upgraded from some 8.x
  release) and the sound worked. Something, that I can't pin down
  changed and now no sound on the system. Some debugging info-

  Mythbuntu 9.04 LiveCD works- volume must be adjusted a bit, but sound plays fine with no other adjustments
  Ubuntu 9.04 LiveCD works- volume must be adjusted a bit, but sound plays fine with no other adjustments
  Fedora 11 LiveCD works- (don't remember if I had to change volume settings)
  Mythbuntu 9.04 installed fails
  Mythbuntu 9.04 installed and upgraded fails
  Mythbuntu 9.10 installed and upgraded fails

  Installed PCI Soundblaster and no luck playing on that either.

  Sometimes after mucking with settings I can get a slight whine out of
  the speakers.

  I ran alsa-info.sh from the ALSA debugging info on both the LiveCD
  boot and the installed system boot. I find an area in the controls
  section suspicious where it seems that the LiveCD instance has less
  controls. I thought that the controls might be getting enumerated
  incorrectly so I used alsactl to store the LiveCD controls. When I
  tried to restore those settings on the installed system the alsactl
  command failed.

  I've done a lot of debugging on this and have had no luck. I ran
  through a few debug/triage procedures with people on an ALSA irc
  channel and got nowhere either.

  I'd be glad to provide any additional information. I've attached the
  alsa-info.sh output for both the LiveCD instance and the installed
  one.
