Register for this notification on audio engine instances, as follows:
When the audio engine’s I/O unit observes a change to the audio input or output hardware’s channel count or sample rate, the audio engine stops, uninitializes itself, and issues this notification. The nodes remain attached and connected with previously set formats. The app must reestablish connections if the connection formats need to change.
