There aren't mixers for Center or LFE at all.  Again going back to my
feelings about mixer names, for the purposes of a laptop I think
providing a knob called Center or another called LFE just adds to the
confusion.

Speaker volume is handled by the combination of Master, PCM, and Front
mixers.  The headphone mixer has no bearing on the volume of the speakers.

If I was to put a vote towards this, I think attempting to support 6
channel analog in the mobile space is a feature that needs to go.  It
causes confusion and complicates the code.

I think knobs, switches, do-hickeys, etc are great to have when they
serve an explicit purpose.  I look at the mixers being presented to me,
and I've no idea what

"Mono Mux" is there for, or why I've got several "Digital Input Source"
areas.

I suppose i've got some confusion for when these commits are showing up
on
http://git.alsa-project.org/?p=alsa-kernel.git;a=history;f=sound/pci/hda/patch_sigmatel.c;h=3c84817ccd2e0d4bd1eee4f2882047ae84165e10;hb=HEAD
My understanding was that the tree alsa-kernel tree was merged into the
alsa-driver and alsa-kmirror trees on a regular basis.  I have been
operating off of web snapshots of alsa-driver from
http://www.alsa-project.org/snapshot/ since I can't do GIT internally
here, but I'm not seeing the patch show up in alsa-driver there.
