But I think this is slightly different. I still want music to stop when getting a call. But I want to be able to start the playback during the call like every other app is able to do.
The feature you linked will disable the stop of music when a call comes in. This is the other way around, right?
You’re right, this is a little different from what I had linked. The root cause seems to be the same though. I just tested on a call and the logs show the following:
2026-08-14 00:30:06.291 Verbose/AudioFocusHelper: Audio focus refused
2026-08-14 00:30:06.291 Error/MusicPlayer: Unable to get audio focus. Skip play.
Symfonium is unable to gain audio focus while a call is ongoing, so it refuses to play media. Meaning that the feature request I linked will at least partially solve your issue (by allowing you to play audio during a call).
I don’t know enough to say if media could still be made to pause when the phone goes off-hook. It doesn’t when using the hack I mentioned in that thread, but that is a hack after all. Actual implementation may behave differently.
