setSpeakerphoneOn static method enabled but audio still coming from earpiece

[cbernatz]

Hi there - I'm setting up my connection and using the Helper to configure the audio to play from the speakerphone on my iOS device:

  if (Platform.isAndroid || Platform.isIOS) {
    _peerConnection!.onTrack = (RTCTrackEvent event) async {
      print('📥 Received remote track: ${event.track.kind}');
      await Helper.setSpeakerphoneOn(true);
      print('🔊 Remote audio track speakerphone enabled.');
    };
  }

For whatever reason, the audio continues top play quietly from the earpiece. Unfortunately, my dependencies only allow me to be on version flutter_webrtc: ^0.11.6+hotfix.1. Can anyone lend any insights as to why this isn't working?
