On 12.4 and I always get dings. I don't even know what app is sending them, since (as other people mentioned), banners do go away. Then, I need to quit (or force quit, because I'm on an important call and can't be checking one app at a time) any and all apps that might send a notification. Even more frustrating is that there's no history of notifications (that I know of, so I can't find out what app was sending those annoying dings and mute notifications from them). So, the problem still very much happens on Monterey. Hopefully, @adrianlondon is right and Mac OS 13 will have the issue resolved. Unfortunately, I can't run off a preview release.
