Subject: ALSA: intel8x0: Fix default inaudible sound on Gateway M520
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=27c3afe6e1cf129faac90405121203962da08ff4;p=openwrt%2Fstaging%2Fblogic.git

ALSA: intel8x0: Fix default inaudible sound on Gateway M520

BugLink: https://bugs.launchpad.net/bugs/930842

The reporter states that audio is inaudible by default without muting
'External Amplifier'. Add a quirk to handle his SSID so that changing
the control is not necessary.
