From 6981d184376e74391c23c116a068f8d1305f0e57 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 15 Apr 2011 10:11:12 +0200 Subject: [PATCH] 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.
