ALSA: hda - Add a fix-up for Acer dmic with ALC271x codec
Acer laptops with ALC271x needs a magic initialization for digital-mic to make it working with mono streams (and PulseAudio). Added a fix-up applied to Acer with ALC271x generically. Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
