https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/893210

it is unlikely fix in alsa driver as pulseaudio expect jack detection kctl 

although js0 ST or js1 ST of ac97 register 0x72 of ad1981b may reflect hp
status


it is not clear how and when to check the change in jack state by timer or
interrept
