Current bug behaviour

During player playback, I want to dynamically switch from speaker to earphone to play, but there is no effect. After switching, the music currently playing will be completely sounded (there was a sound before switching)

Expected behaviour

Dynamically switch from speaker to earphone to playback, and you can hear the current music from earphone normally

Code sample

AudioContext get speakerOnAudioContext => AudioContext(
        iOS: AudioContextIOS(
          /// not silenced
          category: AVAudioSessionCategory.playback,
          options: const {
            AVAudioSessionOptions.mixWithOthers,
          },
        ),
        android: const AudioContextAndroid(
          isSpeakerphoneOn: true,
          stayAwake: true,
          contentType: AndroidContentType.unknown,
          usageType: AndroidUsageType.notificationRingtone,
          audioFocus: AndroidAudioFocus.gain,
        ),
      );

  AudioContext get speakerOffAudioContext => AudioContext(
        iOS: AudioContextIOS(
          /// not silenced
          category: AVAudioSessionCategory.playAndRecord,
          options: const {
            AVAudioSessionOptions.mixWithOthers,
          },
        ),
        android: const AudioContextAndroid(
          isSpeakerphoneOn: false,
          stayAwake: true,
          contentType: AndroidContentType.unknown,
          usageType: AndroidUsageType.notificationRingtone,
          audioFocus: AndroidAudioFocus.gain,
        ),
      );

// init
AudioPlayer.global.setAudioContext(speakerOnAudioContext);
// play
audioPlayer.play(AssetSource(sourcePath));
// switch：then i switch by button:
  final targetContext = currentAudioRoute == speaker
      ? speakerOnAudioContext
      : speakerOffAudioContext;
audioPlayer.setAudioContext(targetContext)

Did you try awaiting the futures before starting playback?

Also I recommed using AudioContextConfig.build instead of using the direct implementations.

I didn't get what you mean, can you give me some codes?

[yoer]

  AudioContext get defaultAudioContext => AudioContext(
        iOS: AudioContextIOS(
          /// not silenced
          category: AVAudioSessionCategory.playback,
          options: const {
            AVAudioSessionOptions.mixWithOthers,
          },
        ),
        android: const AudioContextAndroid(
          isSpeakerphoneOn: true,
          stayAwake: true,
          contentType: AndroidContentType.unknown,
          usageType: AndroidUsageType.notificationRingtone,
          audioFocus: AndroidAudioFocus.gain,
        ),
      );

  AudioContext get earpieceAudioContextConfig => AudioContextConfig(
        route: AudioContextConfigRoute.earpiece,
        respectSilence: false,
      ).build();

  AudioContext get speakerAudioContextConfig => AudioContextConfig(
        route: AudioContextConfigRoute.speaker,
        respectSilence: false,
      ).build();

// init
AudioPlayer.global.setAudioContext(defaultAudioContext);
// play
audioPlayer.play(AssetSource(sourcePath));
// switch：then i switch by button:
  final targetContext = currentAudioRoute == speaker
      ? speakerAudioContextConfig
      : earpieceAudioContextConfig;
await audioPlayer.setAudioContext(targetContext)

is that so?

After I modified this way, after executing the switching code, the music being played can no longer hear any sound (either the headphones or speakers).

[yoer]

After the above modification,

it will take effect on the next player playback (the next player will be played in the headset),

and the current concert will be paused (I feel that the current player.setAudioContext causes the current player to trigger the playback to stop MEDIA_PLAYER_STOPPED)

Now Android can switch earpiece and speakers, but there is no sound when iOS switches from speakers to earpiece.

How to make iOS play in earpiece?
