bluetooth audio in car not working after update (23.4.A.1.232)

[tbird20d]

Bluetooth audio was working fine before the update.  After the update: the phone connects to the car stereo unit (I can tell because the car stereo shows phone info (name, battery level, antenna bars, etc.), but when I play audio there is no sound from the car speakers (or the phone).  Anyone else seen this?  Anything I should try to reset? I tried closing all apps, restarting the phone, and looking in settings for anything that might be affecting the audio routing - but didn't see anything.  Thanks.

Since I bought the Phone I have bring it to the Sony Support 3 times. Because the Bluetooth crashes 30 seconds after it was connected when the Phone was in standby. The last two were at the same month. And they decide to gave me a new Phone. After that it Works properly till the marshmellow update. The diference between this time and the other, one year ago, is that now only crashes when I'm during a conversation and one year ago it crashes automatly 30 seconds after it connects to the car.Do you think it would be a hardware problem?

Thanks for your time.

Does anybody have the same problem?
