    Subject[patch 018/149] ALSA: hda: Use LPIB for Sony VPCS11V9E
    2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

    From: Daniel T Chen <crimsun@ubuntu.com>

    commit e96d3127760a2fc509bca6bf7e61e8bc61497aeb upstream.

    BugLink: https://launchpad.net/bugs/586347

    Symptom: On the Sony VPCS11V9E, using GStreamer-based applications with
    PulseAudio in Ubuntu 10.04 LTS results in stuttering audio. It appears
    to worsen with increased I/O.

    Test case: use Rhythmbox under increased I/O pressure. This symptom is
    reproducible in the current daily stable alsa-driver snapshots (at least
    up until 21 May 2010; later snapshots fail to build from source due to
    missing preprocessor directives when compiled against 2.6.32).

    Resolution: add SSID for this machine to the position_fix quirk table,
    explicitly specifying the LPIB method.
