Load the EAX mod, just follow directions for what supermod you use.
I added in some other sound files from the mod page. I even have one set up where I took some files and replaced others. I added in many of the lines of Gomer, Barney and Earnest T, but it got old after awhile. I'll have to put the video up.
I believe you'll love EAX. It has Poul's sounds added, so give it a try first.
