no, I checked this. It will work if I turn off bluetooth, but I need to leave this on. Any other work arounds?

Then you are probably connected to a bluetooth audio device. If that's the case, the alerts are sent to the bluetooth device. That's entirely normal.

Do not Disturb activated?

Do you see a crescent moon icon at the top of the screen?

I’m having the same issue and my Bluetooth is not turned on. Now, I’m also not getting call sounds!
