Subject: ALSA: hda - Unmute mixer dynamically in alc662 auto-parser
X-Git-Tag: firefly_0821_release~7613^2~1041^2~12^2~77
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0e53f3440925aa36fe3bd2307e5fa0238a66f8bf;p=firefly-linux-kernel-4.4.55.git

ALSA: hda - Unmute mixer dynamically in alc662 auto-parser

Instead of static init array, better to determine the connection and
the mute status of the pin/mixer/DAC route dynamically.  This fixes the
uninitialized mixer 0x0f on ALC892.
