No audio on car after update eos 3.7

Pairing went OK with 3.6 on prius 2015 (pre Android auto)

In 3.7 it says connected for phone and music but only music is played, Phone calls are passed via the car interface and all, but sound is played via the fairphone itself.

Does anybody have a similar experience or a solution?

I strongly suggest to discuss this in the e/OS forum to see if it works with any phone or not in your specific car and car system

I will repost it there then
