Bug description:
  I cannot get the microphone input on my Dell Inspiron 630m laptop to
  work.  I'm using latest dapper, and have tried every possible
  permutation of mixer settings.  I either get a quiet hiss or complete
  silence.

  The sound hardware uses the snd_hda_intel module.  Here's the relevant
  lspci output:

  $ lspci -vv -s 00:1b.0
  0000:00:1b.0 0403: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)

  Googling for this issue suggests that many other people with this
  hardware have this problem too, including this cryptic comment:

  """No mic inputs
  (updated 20/03/2006)

  This is annoying - all of the outputs are doing their thing but not
  the inputs... Presently, the mic/line jack appears to be as dead as a
  doornail. I reckon this is again due to the way this chipset can re-
  task jacks at will, as under windows when you plug a device in it asks
  you "is this a MIC or a Line-level device?"... Presently chatting with
  some Alsa peeps to see if they have any ideas..."""
