I might have found the solution by doing something like this in flutter:

Future<AudioSession> startAudioSession(bool microphone) async {
  var session = await AudioSession.instance;
  if (microphone) {
    await session.configure(const AudioSessionConfiguration.music().copyWith(
        avAudioSessionCategory: AVAudioSessionCategory.playAndRecord,
        avAudioSessionMode: AVAudioSessionMode.measurement));
  } else {
    await session.configure(const AudioSessionConfiguration.music().copyWith(
      avAudioSessionCategory: AVAudioSessionCategory.playback,
      avAudioSessionCategoryOptions: AVAudioSessionCategoryOptions.defaultToSpeaker &
          AVAudioSessionCategoryOptions.allowBluetooth &
          AVAudioSessionCategoryOptions.allowBluetoothA2dp &
          AVAudioSessionCategoryOptions.allowAirPlay &
          AVAudioSessionCategoryOptions.mixWithOthers,
      avAudioSessionMode: AVAudioSessionMode.measurement,
    ));
  }
  await session.setActive(true);
  return session;
}

Can you provide some details? I am facing some issues with iOS. AudioSession is something from flutter?

from cpal.

Audio Session is a flutter pacakge, it can manage your iOS AVAudioSession. It seems like cpal fails to do so (I don't know if by design or not?), and you have to configure and start the audio session yourself.

Maybe coreaudio-sys / coreaudio-rs could help.

I think this is only an issue since iOS 17

from cpal.
