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 0 (via the load resistor pull-down action).
IN = Jack has plug inserted, and therefore the JS status is 1 (via the codec JS pin internal pull-up).
Note: MMDIS (Reg 0x70 Bit D7) set to 1 will keep Mono Out enabled for all settings above.
