I wonder if you have tried to long press on these annoying China apps in the pull down notification panel and when the app settings open, you can off the app's notification?Yes MIUI China rom will get this kind of problem. It also comes with many ads in built-in app. Try not to use China MIUI.

I did that for every China app that make annoying sound when something appearing in the pull down notification panel. Now my Mi Max is mostly quiet.
