I have that as well, probably started about 2 weeks ago. If I select phone as an audio source it works (ie spotify or something like that). When a call comes in I can answer it on the touch screen but I hear no audio and it appears that the phones mic is still active. If I listen on the phone I can not hear the caller but if I activate speaker on the phone I can. Same if I make a call. I have tried rebooting phone and car, and have unpair/forgotten connection on car and phone and repaired with no change. Has it been fixed for you guys? (on 2021.36.5.8)
