[BUG]3.14-rc2 [PATCH] Revert "ALSA: hda/realtek - Avoid invalid COEFs for ALC271X"

[Martin Kepplinger]

This reverts commit d3c56568f43807135f2c2a09582a69f809f0d8b7.

The reverted commit breaks audio through headphone line out on
the Acer TravelMate B113 (Type1Sku0) Notebook, my main work
machine. I don't know much about it but this fixes my problem.
Bisected and tested.

Too bad, we need COEF for some machine but it breaks for some.
Since reverting breaks obviously another machine, we need a different
approach, e.g. checking the machine ID.  Please give alsa-info.sh
output of your machine.


thanks,

Takashi

Thinking it again, I'll take your patch as is, and put an additional
fix for AO725 as below.  Could you try it to see whether it brings any
regressions?  It's to be applied after your revert patch.

Subject: [PATCH] ALSA: hda - Better fix for invalid COEF setup on Acer AO725

Instead of disabling the COEF setup for all ALC271X codec (like commit
d3c56568), do it only if needed.  Currently, Acer AO725 is known to
show the problem, so clear the bad init_hook in the fixup.

The explicit call of alc269_fill_coef() in patch_alc269() is also
removed, since the function will be called anyway at init callback.

So my alsa-info.sh is
http://www.alsa-project.org/db/?f=3e9c5d39ff057106d6ae307f9b86c1e562056c1b
and I'm running your patch on top of mine without any problems.

thanks,

OK.  I queued the patches now.
Thanks!
