If anyone has any objections, please let me know. ------------------ From: Daniel T Chen 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.
