Hi,

Attached is a patch against current sound-2.6 master HEAD enabling audible playback from the LG P1 Express's internal speakers. Capture and jack sense were also verified working. This patch is also applicable to all stable, supported kernels. Please apply.

Applied now to sound git tree. Thanks.

Takashi

BugLink: https://launchpad.net/bugs/595482

The original reporter states that audible playback from the internal speaker is inaudible despite the hardware being properly detected. To work around this symptom, he uses the model=lg quirk to properly enable both playback, capture, and jack sense. Another user corroborates this workaround on separate hardware. Add this PCI SSID to the quirk table to enable it for further LG P1 Expresses.
