[ALSA] hda-codec - Support multiple headphone pins
Some machines have multiple headpohne pins (usually on the lpatop and on the docking station) while the current hda-codec driver assumes a single headphone pin. Now it supports multiple hp pins (at least for detection). The sigmatel 92xx code supports this new multiple hp pins. It detects all hp pins for auto-muting, too. Also, the driver checks speaker pins in addition. In some cases, all line-out, speaker and hp-pins coexist. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>
