Subject: ALSA: hda - Auto-mute all LO and speakers in patch_via.c
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=64be285b669e5eed65fb3630f1b2b549447b9f1e;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Auto-mute all LO and speakers in patch_via.c

Muting all line-outs and/or speakers is more common in other drivers,
so we should follow it, too.
