Subject: ALSA: hda - Use always amps for auto-mute on AD1986A codec
From: Takashi Iwai <tiwai@xxxxxxx>
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.
