The entire audio graph must be destroyed, audio device re-enumerated, and a new audio graph created since the various channel counts and formats could have changed.
	OnProcessingPassEnd	Called by XAudio2 just after an audio processing pass ends.
	OnProcessingPassStart	Called by XAudio2 just before an audio processing pass begins.
