    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.
