Title should have said NO sound. I have not driven much since the latest update 2021.4.15. Today for the first time since update, I noticed that my radio does not connect to the speakers. The radio recogizes the station and current programing on all ststions tried. But there was no sound. I tested the sound on all other scources and it worked normally. I tested on all radio stations available and it did not. I am wondering if other Tesla owners have experienced this problem.
