Same problem here, my code :

`AudioCache audioCache = new AudioCache(prefix: 'assets/audio/', respectSilence: widget.settings.respectSilence); File audiofile = await audioCache.load('alarm.mp3');

  AudioPlayer advancedPlayer = AudioPlayer();
  final result = await advancedPlayer.earpieceOrSpeakersToggle();
  if (Platform.isIOS) advancedPlayer.monitorNotificationStateChanges(monitorNotificationStateHandler);
  await advancedPlayer.play(audiofile.path, isLocal: true, respectSilence: widget.settings.respectSilence, volume: widget.settings.chronoVolume);`

The only solution i found : do the earpieceOrSpeakersToggle method in a try/catch in init.

Maybe allow to define the PlayingRouteState in constructor ?

[luanpotter]

you have to call play or setUrl first I think. definitely a bug, you should be able to call it whenever like the other methods.

Hello! Unfortunately this bug still exists, so I have to use platform native code to deal with switching to earpiece and back. earpieceOrSpeakersToggle method in a try/catch also not working at all. Please answer me if there is any simple workaround/solution.

This method doesn't exist anymore. Closing in favor of #1240
