Subject[PATCH 01/23] ALSA: hda: Use model=lg quirk for LG P1 Express to enable playback and capture review patch.  If anyone has any objections, please let us know.


From: Daniel T Chen <>

commit 77c4d5cdb81d25a45fbdfb84dd3348121219a072 upstream.


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.
