Play sound through loud speaker

[Immons]

Hello,

Thanks for binding libs. Have you maybe figured out how to play sound through loud speaker? Tried to iterate through SpeakerList, but there is only one, default and it plays through phone speaker.

Best regards

Hi @Immons , you need to do this per platform. I do it when call state changes to "Connected". On Android:

private void SetSpeakerOutput()
  {
      _logger.Debug($"Trying to route audio volume to speaker and set volume to max");
      var audioManager = (AudioManager)MainActivity.Instance.GetSystemService(Android.Content.Context.AudioService);
      if (audioManager == null) throw new Exception("No audio manager");
      audioManager.Mode = Mode.InCall;
      audioManager.SpeakerphoneOn = true;
      audioManager.SetStreamVolume(Stream.VoiceCall, audioManager.GetStreamMaxVolume(Stream.VoiceCall), VolumeNotificationFlags.ShowUi);            
}

On iOS:

private void SetAudioToSpeaker()
{
    try
    {
        _logger.Debug($"Trying to route audio volume to speaker and set volume to max");
        var error = AVFoundation.AVAudioSession.SharedInstance()
            .SetCategory(AVFoundation.AVAudioSessionCategory.PlayAndRecord,
                AVFoundation.AVAudioSessionCategoryOptions.DefaultToSpeaker);
        ThrowIfError(error);
        AVFoundation.AVAudioSession.SharedInstance()
            .SetMode(AVFoundation.AVAudioSession.ModeVoiceChat, out error);
        ThrowIfError(error);
        AVFoundation.AVAudioSession.SharedInstance()
            .OverrideOutputAudioPort(AVFoundation.AVAudioSessionPortOverride.Speaker, out error);
        ThrowIfError(error);
        error = AVFoundation.AVAudioSession.SharedInstance().SetActive(true);
        ThrowIfError(error);
        _logger.Debug($"Finished audio setup");
    }
    catch (Exception e)
    {
        _logger.Error("audio_setup_failed", e);
    }
}
