    Console.WriteLine ("_AudioRendererFlushTime", args._AudioRendererFlushTime);
});

// To stop listening:
notification.Dispose ();

//
//Method style
//
NSObject notification;
void Callback (object sender, AVFoundation.AudioRendererWasFlushedAutomaticallyEventArgs args)
{
    // Access strongly typed args
    Console.WriteLine ("Notification: {0}", args.Notification);

    Console.WriteLine ("_AudioRendererFlushTime", args._AudioRendererFlushTime);
}

void Setup ()
{
    notification = AVSampleBufferAudioRenderer.Notifications.ObserveAudioRendererWasFlushedAutomatically (Callback);
}

void Teardown ()
{
    notification.Dispose ();
}

// Listen to all notifications posted for any object
var token = AVSampleBufferAudioRenderer.Notifications.ObserveAudioRendererWasFlushedAutomatically ((notification) => {
	Console.WriteLine ("Observed AudioRendererWasFlushedAutomaticallyNotification!");
};

// Listen to all notifications posted for a single object
var token = AVSampleBufferAudioRenderer.Notifications.ObserveAudioRendererWasFlushedAutomatically (objectToObserve, (notification) => {
	Console.WriteLine ($"Observed AudioRendererWasFlushedAutomaticallyNotification for {nameof (objectToObserve)}!");
};

// Stop listening for notifications
token.Dispose ();
