Subject: [PATCH 3.11 081/208] ALSA: hda - Use always amps for auto-mute on AD1986A codec

3.11.10.2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@...e.de>

commit b3bd4fc3822a6b5883eaa556822487d87752d443 upstream.

It seems that AD1986A cannot manage the dynamic pin on/off for
auto-muting, but rather gets confused.  Since each output has own amp,
let's use it instead.
