Subject: [ 114/167] [PATCH] ALSA: HDA: Add external mic quirk for Asus Zenbook UX31E

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

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

From: David Henningsson <david.henningsson@...onical.com>

commit 5ac57550f279c3d991ef0b398681bcaca18169f7 upstream.

According to the reporter, external mic starts to work if the
laptop-dmic model is used. According to BIOS pin config, all
pins are consistent with the alc269vb_laptop_dmic fixup, except
for the external mic, which is not present.
