Need to get route change notification for MPMoviePlayerController

Question

Need to handle event with hands free(ear phone). It is not working with .AVAudioSessionRouteChange. Please suggest. Here is how observer added:

NotificationCenter.default.addObserver(self,
                                           selector: #selector(handleRouteChange),
                                           name: .AVAudioSessionRouteChange,
                                           object: AVAudioSession.sharedInstance())
