FMUTE = Output is forced to mute independent of the respective volume register setting.
ACTIVE = Output is not muted, and its status is dependent on the respective volume register setting.
OUT = Nothing plugged into the jack and, therefore, the JS status is low (via the load resistor pull-down).
IN = Jack has plug inserted and, therefore, the JS status is high (via the codec JS internal pull-up).
