First play a music then they will give a pop up that shows which play you wanna choose

it's done but pressing the play button on my U flex headset still opens Samsung music app. can it be changed.

Did you select the favorite app on play button in sound assistant?

Samsung music is selected but when I select Poweramp it disables the favourite app . Seems like it takes Samsung music by default.
