Hello! After the latest update our 2021 Model S blares the external speaker when we turn on the car (much to the dismay of our neighbors). Once we begin driving, the interior speakers will alternate between a high pitched sound and blaring the music at max volume. While driving we have no volume control. We have tried holding down scroll wheels to reset but no luck. Have requested service but soonest appointment they can give us is mid December. Grateful for any suggestions.
