Just happy to help (I have not been doing enough of that lately).
Perhaps a bit of a cheater approach (I'd rather give a proper explanation which would provide decisive and informed control but I have none) but really there so much to keep track of I've gotten to the point of "make it bloody work and I'll sort out the fancy crap if it starts holding me back).
In this case... I really have no love for system sounds. I don't need little beeps, squonks and strange sounding computer ladies yelling at me all the time. It's annoying and often times jarring/frightening. I hate listening to something intently with my entire pea brain focusing on something then getting blasted by some MS sound. Puts me in "fight or flight" mode for a second which is extra bizarre when you're sitting in a room totally by yourself.
lulz...
Cheers.
