Bug description:
  The sound device model probing is broken in 2.6.27. As a result, the
  sound device is missing large functionality, including any use of the
  microphone, and headphone port.

  Using the model=mbp3 option on snd-hda-intel as described here:
  http://git.alsa-project.org/?p=alsa-
  kmirror.git;a=blob_plain;f=Documentation/ALSA-
  Configuration.txt;hb=HEAD restores the previous functionality.

  Workaround: append the line "options snd-hda-intel model=mbp3" to
  /etc/modprobe.d/alsa-base and reboot.
