    Subject[PATCH 3.8 20/81] ALSA: hda - Fix microphone for Sony VAIO Pro 13 (Haswell model)
    Date
    3.8.13.12 -stable review patch.  If anyone has any objections, please let me know.

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

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

    commit 88cfcf86aa3ada84d97195bcad74f4dadb4ae23b upstream.

    The external mic showed up with a precense detect of "always present",
    essentially disabling the internal mic. Therefore turn off presence
    detection for this pin.

    Note: The external mic seems not yet working, but an internal mic is
    certainly better than no mic at all.
