Should these elements be muted in other paths?

Title:
  pulseaudio does not recognize internal speakers [P180HMx, Realtek
  ALC892, Speaker, Internal] volume slider problem

Status in “linux” package in Ubuntu:
  Fix Committed
Status in “pulseaudio” package in Ubuntu:
  In Progress

Bug description:
  steps to reproduce:  
  1.  acquire a device with the problem, such as Clevo P180HM laptop motherboard 
  2.  install ubuntu 12.04  (now updated to 12.04.3 currently) 
  3.  systray > speaker-icon > sound-settings > output tab  
  4.  no entry for "speakers built-in audio" appears 

  workaround:  
  running the shell script mentioned in this comment helps -- 
  https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/946232/comments/158 

  however, the workaround is not completely satisfactory, because 
  adjusting the (singular) volume-slider provided by pulseaudio only 
  causes some of the (multiple) volume-sliders known to alsamixer to react. 
  Specifically, turning the pulseaudio volume upwards only changes the 
  'master' and belatedly the 'pcm' volumes inside alsamixer.  This ignores 
  'speaker clfe' + 'speaker front' + 'speaker surround playback volume' 
  plus maybe others.  Effectively, this means audio playback is weak:  instead 
  of spreading typical 2ch audiofiles across all internal speakers, only some 
  are used, and only at whatever volume alsamixer specifies.  (Turning the 
  ignored volumes up in alsamixer causes a different problem:  then it is no 
  longer possible to lower the sound to a relatively-quiet volume.)  

  Here is some information from one of the ubuntu pulseaudio/alsa devs:

  ...you have unusual hardware: in addition to normal
  headphones and stereo line out, you have 5.1 internal speakers. This
  leads to unusual alsamixer names (e g "Speaker Front") which we do not
  match for in PulseAudio. Fixing that means that we should add those
  names in PulseAudio - but let's discuss that in a new bug instead.

  Let me know if you would like more specifics.  I have run codecgraph,
  alsa-info, etc.
