Thanks, I applied this to for-next branch, as this is the behavior
fix. The copy of front channels are intentional in the current code,
so the patch isn't a "fix" but rather an enhancement, IMO.

Title:
pulseaudio does not recognize internal speakers [P180HMx, Realtek
ALC892, Speaker, Internal] volume slider problem
Status in “alsa-driver” package in Ubuntu:
New
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.
