I am running a pi3B+ and the latest image of M2P fully updated. I can connect to the Sony car stereo on my boat, but no audio plays. When I connect to generic bluetooth speakers, everything works as expected. When I connect my phone via bluetooth to the stereo, it works as expected.
I have tried repairing and reconnecting, but to no avail. The stereo shows that the it is connected and M2P shows that the stereo is connected, but there is no audio.
Is there some setting that I have missed that is specific for car stereo type bluetooth applications? Any thoughts, tips or tricks to get this working?
