I have successfully got a bluetooth speaker connected to my Pi 3 B+ and using abcde to rip CD's and Mopidy to play them.
However everyone I reboot, the volume control is disabled and audio out is not connected to bluetooth. My .asoundrc file contains the following:-
If I open the Audio preferences select Also and click set as default, the Volume button is then enabled and I can select the bluetooth speaker as the audio output.
How do I configure this so that the bluetooth connection is maintained after a reboot.
