try to find out the VAL return by get pin sense after those unsolicited
events
`hda:hda_send_cmd` traces each CORB write while `hda:hda_get_response`
traces the response from RIRB (only when read from the codec driver).
The generic parser supports the following hints:
- trigger_sense (bool): indicates that the jack detection needs the
explicit call of AC_VERB_SET_PIN_SENSE verb
you can disable set_pin_sense ( start impedance measurement on some hda
codec which support impsense) by specify hint
trigger_sense = false
check whether only one unsolicited event for the plugged jack
