Yes, it's OK to do this - we're guaranteed that the device is already
enabled at the time we decide to start the microphone detection (as
we're in the middle of examining the state which needs a runtime
reference).  We're taking an additional reference here so that the
device doesn't get powered off again after the event has been handled.
