Make sure the front speaker in the bumper is plugged in on the passenger side? My sounds were quiet and I ended up looking and it was never plugged in.I just updated to version v12 (2024.20.1 831cee498fc0) and now the Boombox, Megaphone, sound is very low. Previously it did get louder, and I preferred it that way. Now it's very low. I would hope they would code in a volume control for the Megaphone, and lock sound.
