Hi!
It seems that snd_hda_intel driver fails to detect hp/mic/line jack
presense with ALC883 codec.
According to Realtek's specs (and practice) ALC883 doesn't generate
unsolicited events in this case, so the only way to detect jack is to
periodically poll appropriate pin complex with AC_VERB_GET_PIN_SENSE.
AFAIK, there is currently no way to do such thing.
The idea is to add a new function to hda_codec_ops:
void (*poll)(struct hda_codec *codec)
and run it as a separate thread after codec init phase is done.
What do you think?
Andrew.
