Yeah PA knows about the two different paths - Internal Mic and
[External] Mic. Whichever one is being used will be controlled by the
volume slider in PA mixers, and the one not in use is zero'ed out. So
this is the expected behaviour.

In the future, when an external mic is plugged in it'll automatically
activate. David is working on that now.

pavucontrol can split the channels if there are more than one and let
you control each individually. Just press the "lock channels" button.
