Current bug behaviour

In API 23, when I pause or stop Media Player running with loop mode, I get the next error and player never stops:

E/MediaPlayer( 3828): pause called in state 8 E/MediaPlayer( 3828): error (-38, 0) E/MediaPlayer( 3828): Attempt to call getDuration without a valid mediaplayer E/MediaPlayer( 3828): error (-38, 0) E/MediaPlayer( 3828): Attempt to call getDuration without a valid mediaplayer E/MediaPlayer( 3828): error (-38, 0) E/MediaPlayer( 3828): Attempt to perform seekTo in wrong state: mPlayer=0x7654172180, mCurrentState=0 E/MediaPlayer( 3828): error (-38, 0) E/MediaPlayer( 3828): Error (-38,0) E/MediaPlayer( 3828): Error (-38,0) E/MediaPlayer( 3828): Error (-38,0) E/MediaPlayer( 3828): Error (-38,0) I/flutter ( 3828): AudioPlayers Exception: AudioPlayerException( I/flutter ( 3828): AssetSource(path: sounds/alert.mp3), I/flutter ( 3828): PlatformException(AndroidAudioError, MEDIA_ERROR_UNKNOWN {what:-38}, MEDIA_ERROR_UNKNOWN {extra:0}, null)

Expected behaviour

Stop playing audio in API 23. It works well in API < 23.

Steps to reproduce

1. Play an audio file in loop mode.
2. Stop/pause Media Player.

Code sample

Code sample

audioPlayer = AudioPlayer();
await audioPlayer?.setSource(AssetSource(soundPath));
audioPlayer?.setReleaseMode(ReleaseMode.loop);
...
audioPlayer?.resume();
...
audioPlayer?.stop();

I discovered that if I use lowLatency Player Mode it works well.

audioPlayer?.setPlayerMode(PlayerMode.lowLatency);

I use Android 12, and audioplayers has the same issue. it works, thankyou @marc7garcia . But for long media files or streams, lowLatency has some limitations.

[BirgitPohl]

I get the same error. Not running it in loop mode. But simply re-initiating the player and setting a different source. Running on Android 14.

So, I simply call _audioPlayer.setSourceUrl(_currentAudioLesson.audioUrl!);

audioPlayer?.setPlayerMode(PlayerMode.lowLatency);

It seems, this causes trouble with audio position and audio duration. The values are 0 when I use this line.

Thank you for the report. It is hard for us to support all devices. We're happy if you could help us fix this. Keep in mind, that we're currently working on using Exoplayer instead.
