The Media Session raises this event if it receives any of the following events from the media sink:

• MEAudioSessionDeviceRemoved

• MEAudioSessionDisconnected

• MEAudioSessionExclusiveModeOverride

• MEAudioSessionFormatChanged

• MEAudioSessionServerShutdown

A media sink can also raise this event, in which case the Media Session sets the MF_EVENT_OUTPUT_NODE attribute on the event and forwards the event to the application.
