My Samsung 51A phone connects to my car just fine via Bluetooth but the audio no longer works. All audio and media settings are correct. Car says to turn the BT audio up on the phone but doing so immediately sends the phone's volume bar into the red and the audio still doesn't play. BT audio worked fine yesterday but, since then, I installed the suggested Bixby update (which I never use). Is Bixby the problem? How do I fix this problem?? Using Android Auto doesn't work either. I want to play my audio books!
