is there any need to has a control ’headphone as line out’ to change
pinctl from OUT HP to OUT ?
do popup window ask you to determine the type when you plugged in the

the node support impsense,can it determine the plugged in type be
measure the impedance since Mic Jack has higher impedance than the
headphone or speaker
