[iOS] App launch instantly kills background audio

[qu0cquyen]

When launching the app on iOS, any currently playing background media (e.g., Spotify, Apple Music) is instantly paused/killed. This happens immediately upon app initialization, well before the user actually initiates or joins a StreamCall.

Dart-level configurations (such as passing a custom AudioConfigurationPolicy to StreamVideoOptions or using the audio_session package to force mixWithOthers) are ignored or instantly overridden because the underlying native WebRTC RTCAudioSession singleton aggressively claims the AVAudioSession upon plugin registration.

Steps to Reproduce

Start playing music on an iOS device via Spotify or Apple Music.
Launch the Flutter application

stream_video: ^1.3.1
stream_video_flutter: ^1.3.1
stream_video_push_notification: ^1.3.1
stream_video_screen_sharing: ^1.3.1

Hi @qu0cquyen, apologies for the delayed response. Can you confirm that it is also happening for you on our dogfooding app?

Hi @Brazol,

Sorry for the late reply. This doesn't happen on example dogfooding app.
I'll need to re-check my app's initialization. But if you've come across knowing why this happen with us, we would really appreciate if you can give us some hints on fixing this issue.
