Need to know what if anything ever worked. Its driving my passengers and I crazy. My chime is also disabled in android auto menu and I still get an obnoxious notification chime.I tried that first and it did not work. Maybe it is timing as the chime is quick. Will try again.
I figured out why the Volume selection does not stick: The selected message Chime Volume is also the volume for Phone Command Responses when responding to voice input, like Hey Google or pressing the Assistant button on Android Auto.I did catch it, but it does not seem to stick... Annoyed the hell out of me on a long drive this weekend.
