How disable sounds?

Hello, as I turn off those silly sounds in alerting the firewall? I can’t find any option. The latest user environment is a horrible, tedious and confusing! Chcio the old practice of the previous versions. It comes somehow set up? Thx

I made a video showing how here: How to turn off alert sounds in CIS - YouTube

If you require instructions in text then please tell me and I’ll provide that.
