[PATCH 4.4 124/137] ALSA: hda - fix front mic problem for a HP desktop
From: Greg Kroah-Hartman
Date: Sun Apr 17 2016 - 22:40:16 EST
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hui Wang <hui.wang@xxxxxxxxxxxxx>
commit e549d190f7b5f94e9ab36bd965028112914d010d upstream.
The front mic jack (pink color) can't detect any plug or unplug. After
applying this fix, both detecting function and recording function
work well.
