Subject: ALSA: hda - Fix ALC268 parser for mono speaker
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3f3b7c1aed70fa25c6811f830c5fb1a7054681ae;p=openwrt%2Fstaging%2Fblogic.git

ALSA: hda - Fix ALC268 parser for mono speaker

- Parse the mono output pin 0x16 correctly even as the primary output
- Create "Speaker" volume control if the primary output is a speaker
- Fix the wrong direction of (optional) "Mono" switch
