What audio are you playing? Can you state the source? Can you insert the logs plz? Thx :)

[docaohuynh]

@Gustl22 I run on example source https://github.com/bluefireteam/audioplayers/tree/main/packages/audioplayers/example
It is not play any source at on. I was not seen logs in my device

Did you follow these steps: https://github.com/bluefireteam/audioplayers/blob/main/contributing.md#environment-setup ?
So you use the latest version on branch main?

Does it work on your emulator?

I tried it right now and the source is playing without issues. I cannot reproduce it :/

[docaohuynh]

Did you follow these steps Yes
So you use the latest version on branch main? Yes

@Gustl22 I had tested on 4 devices but this only happened on Oppo F1s (android 6)

Thanks @docaohuynh, do these devices run all on Android 6? Maybe this can be solved via #1526. I don't think it's directly related to AudioPlayers but rather a fault in the Android native implementation.

[docaohuynh]

@Gustl22 Only Oppo F1s run Android 6 others Android 9, 12, 13. I don't have other device run on Android 6 to tested. waiting for ExoPlayer implement

Same problem

[Kind-Unes]

any solutions ?

[Gustl22]

The solution is probably #1691, but it takes a while for Flutter to review all the necessary PRs.

Previously my code was like :
final audioPlayer = AudioPlayer();
audioPlayer.setSourceUrl("https://www.learningcontainer.com/wp-content/uploads/2020/02/Kalimba.mp3");
I ran thorugh error :
PlatformException(AndroidAudioError, Failed to set source. For troubleshooting

After sometime it trigggered as it was just async await issue of url. Since, url sends some data to audioplayer to play at first
It need sometime to init and which was causing the error of playing on the first step itself.
Simply putting
"await" helped me !!

solved code:
final audioPlayer = AudioPlayer();
await audioPlayer.setSourceUrl("https://www.learningcontainer.com/wp-content/uploads/2020/02/Kalimba.mp3");
