LG G5 H850 bluetooth not working in car

Hello folks,

I got my G5 H850 working with /e/ OS for a few days now. All in all most of the things are working fine. What I’m disappointed by now is the bluetooth functionality with my car. The person at the other end of the line only hears an awfully noise, where my voice is almost being swallowed up. Also the voice from the other person through my car speakers is very noisy. I had this issue on two G5 H850 by now, whereas the same hardware works fine on stock Android Oreo regarding bluetooth. Besides that, /e/ OS an the G5 are a good couple, but the bluetooth functionality is a must for my daily use. With my good old Nokia 6303i I never had such issues.

Is there any way out of this situation? Might it work with Lineage OS 17.1 or is this a generally driver related issue with lineage based systems?
