No sound in Android Auto wired head unit if DVC is on and Media Volume = 0

Device: Oneplus 5T

Rom: Stock Oxygen 9.0.2 (Android Pie 9.0)

I am not sure if it is intended, but if DVC is on and Media Volume = 0, then there is no sound is Android Auto wired head unit. If DVC is off or I turn up Media Volume, then I have sound in Android Auto head unit. Besides, if it is normal that Android Auto wired head unit is recognized as Speaker in Output settings?

Same happens to me. This needs to be fixed so annoying. Turning off DVC doesn't sound as good as when it's on
