Is it possible to control a2dp profile when starting music player?

[AC Question]

I'm looking for an app, that could control the a2dp profile when starting the music player. My scenario is: In my car the phone is connected to BT and the car speakers. The phone reads out incomming text messages via the app Drivemode. These messages comes through the phone speaker, as I've disabled A2DP in the BT-profile. When I starts my musicplayer, and want to listen through the car speakers, I switch to Bluetooth input in the car, and I must go to settings - bluetooth - and change the profile to use A2DP. I would like to have an app that could change the BT-profile when I starts the musicplayer.

Hope it makes sense for you guys

Any help would be appreciated.
