ALSA: hda: Use LPIB for Sony VPCS11V9E
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.
