di you also try identifing "music player" as game, and then adjust gaming options?I have one feature request - disable sound on notifications when music is playing.
Right now I'm using MacroDroid which works, but there is an issue - if I turn on vibrate manually on slider, then play some music and stop it - MacroDroid automatically disables vibration even when slider is in vibrate position.
#edit
Okay, played with MacroDroid after posting this, managed to achieve this! Posting screenshot if someone wants to use the same approach![]()
(not sure, could be a solution without esternal app)
