Yes, in fact, before writing, check that the applications were in the list (my game and Poweram Full, to put the switch on off, but neither of the two appear, only Spotify appears, it is something strange, that is why I reached the forums to ask for help.
Don't you have to make some configuration in the full Poweramp app to prevent it from calling the EQ application?
There I uploaded a screenshot, it does not show Poweramp full or my game diablo immotal and when I open either of these two applications, at the top of the notification bar it shows that it is equalizing through the Poweramp EQ and I don't want that.
I don't want Poweramp Full to have double equalization, if it already has its own, if you know anything about it I would appreciate it.
Note: I have the app installed on my Samsung cell phone. Sound Assistant
