FLAC Player

OK perhaps we're getting to the point. It might be your Clarion car stereo, because some bluetooth device can send a "play" command to the bluetooth sender when connection is established or dropped. What happens if you disconnect the Clarion and connect the bluetooth to some other device, same problem?

Anyway I am googling about your problem and there's other people complaining as well. I found a page with lots of suggestions on how to deal with the problem, that's it: How to Stop Apple Music From Opening Automatically On Mac

hope it helps

 

Yea I don't know about that kinda stuff....

My iPhone Podcast and Music would do it with the Clarion and my Tundra truck.

BUT only Apple apps. I replaced Music with Vox and podcast with Overcast and these apps don't do it.

Audirvana does not do it either.....

Thanks for the hints! The techs and I tried everything. I'm thinking there must be a Terminal hack that bricks it but as of yet nothing that address this. I found one for the F8 "play" key doing it but that's not my issue.
