Bug description:
  Binary package hint: pulseaudio

  Hi, this might not be a bug in pulseaudio but I wasn't sure of the
  right package for this.

  Basically each of the volume controls in gnome seem to control the
  wrong mixer channel.

  The exact device ID is:

  00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
  00:1b.0 0403: 8086:27d8 (rev 01)

  Sliding the volume control with alsamixer open, I see behaviour where
  at the top 80% of the volume range, the Master level is changed from 0
  to 100%.  In the ~5% or so below that, the LFE level is changed from 0
  to 100%.  In the bottom ~15%, the PCM level is dropped.

  This seems like quite deliberate behaviour, but for this laptop it is
  entirely inappropriate.  Between the 15% and 20% setting for instance
  the subwoofer speaker goes from 0% to 100%, with the treble speakers
  off.  It sounds *awful*!

  More appropriate behaviour for this laptop is to have LFE at ~100% and
  Master at ~85%, and then just changing PCM between about 100% and 25%
  will give good levels for most environments.  Alternatively, you can
  adjust both LFE and Master together - ideally with LFE slightly higher
  than Master - and leave PCM on high and this will achieve a similar
  effect.
