Im looking for a Working Koob from Chapt 20

Hey all
Ignore my previous post - Im way beyond that now :-0 !
what I am asking for (pleading for actually!) is if someone would be kind enough to send me a working
version of Koob from chapter 20 so I can move ahead with sound that works
(and use it to cross check where mine had errors)

My central problem is that my Audio Driver will not load

Thanks for any assistance
J.
