I am also having this problem, I have a 2019 Hyundai Kona, it does have android auto, but I generally just open the app, version 2205.1.1, but for the last two weeks it will connect, the songs will show on my touch screen, but no sound comes out.

My phone is a Motorola one 5g running android 11. I have tried forgetting the phone in the Kona, deleted the app and reinstalled it. Neither worked.
