On a completely different tack and not a lot to do with the sound problem, these days, you buy something and there's no "instruction book" any more. It seems to me that purveyors of technical goods seem to think that buyers will find it "fun finding out". Now that might be so for people who never actually do anything, but just love fiddling about whereas others want to get on with the job that they bought the item to do.
There doesn't seem to books about such things any more either, just loads of links to some website or other. I don't know how long you've been in to Windows, but my first experience was Windows 95. There was a book available, "Windows 95 Secrets", it ran to over 1200 pages! Now that's some collection?
Getting back to the sound issue, I'm a user, not a fiddler, I want to get on with things. Currently I'm proof reading a 1300 page document. The program I'm using opens only in a window. Usually I use tabs. I usually have three tabs open and when I'm using the word processor program, the Window obscures my three tabs, two of which are my email adresses so that's why I want a sound when an email arrives. Currently, I've dragged the top of the Window down so I can see the three tabs but I'd rather not. Time I went, goodnight
