Pretty sure you want enforcing. Permissive is huge security risk and breaks safetynet.... Then again Idk how android 11 would work. on oos android 10 oneplus 7 pro. Tell me if you get app working on enforcing lolHay, i am experiencing a bug whereby one app is muted while the other app sound continues. As soon as i pause the latter, sound from the other app starts working(Audio Focus ignored on both apps). [Oneplus 6t running PiXeN Os 11]
Edit: SeLinux issue xD... Didn't know my kernel was enforcing(First time).
The xda article about this app states (emphasis mine):
So how do I go about actually forcing two or more apps to play audio simultaneously (for example twitch+Spotify, YouTube music+YouTube, etc)? I could find no way to do that inside the app
