X-Git-Tag: v3.1-rc2~4^2~47^2~68
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6d86b4fb407995081c85106188e2d2404529d71c;p=platform%2Fkernel%2Flinux-3.10.git

ALSA: hda - Fix auto-init of output volumes of Realtek codecs

Fix the regression introduced by the commit
1f0f4b8036b1fe1347cb4f1f199601b87de9be46
  ALSA: hda - Reduce static init verbs for Realtek auto-parsers

The input amps of mixer widgets should be unmuted as default (as
usually they have no assigned mixer switches).

More fixes in this commit are, however, for ALC260: ALC260 codec can
have multiple output mixers connnected to a single DAC althouh the
driver didn't pick up them properly.
