Steps to reproduce
I wanted to report a problem I encountered when I upgraded to Flutter 3.35.1 and Dart 3.9.0
My configuration of audio_service 0.18.18, just_audio 0.10.4, audio_session 0.2.2 The app works perfectly with foreground word and background music with my Samsung S20 FE with android 13. With the Samsung S24FE with android 15 it has problems. When I insert the background it creates like a conflict and it has like an endless loop, sometimes it stops and then starts again.
Problem with android 15 but not with android 13
Translated with DeepL.com (free version)
The problem can also be reproduced in the example file if you use main.dart. If you launch it in Android 13 with the above configuration it works fine. If you launch it with Android 15 it does not work and gives the same error that it gives me too https://github.com/ryanheise/audio_service/blob/minor/audio_service/example/lib/main.dart

Expected results
I expect it to simply play correctly as it does with Android 13
Actual results
It does not sound correctly

I am currently in the middle of another migration, so I can't upgrade the SDK just yet. If example/lib/main.dart fails as you say, then it should be easy for me to reproduce when I can try it.
There's news, Rayan. Android is pushing for my app to be updated to a target higher than 34, and until this issue is resolved, I'm staying put. Thank you, as always.
Good news, Rayan. With the latest update you made to just_audio 0.10.5, the problem has been resolved. So the problem was related to just_audio and not to audio_service. Keep up the good work.
