[PATCH 3.14 043/238] ALSA: hda - Fix COEF setups for ALC1150 codec

From: Greg Kroah-Hartman
Date: Fri Oct 03 2014 - 19:58:45 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

commit acf08081adb5e8fe0519eb97bb49797ef52614d6 upstream.

ALC1150 codec seems to need the COEF- and PLL-setups just like its
compatible ALC882 codec. Some machines (e.g. SunMicro X10SAT) show
the problem like too low output volumes unless the COEF setup is
applied.
