    Subject[PATCH 4.2.y-ckt 30/70] ALSA: hda - fix front mic problem for a HP desktop
    Date
    4.2.8-ckt8 -stable review patch.  If anyone has any objections, please let me know.

    ---8<------------------------------------------------------------

    From: Hui Wang <hui.wang@canonical.com>

    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.
