Hi Zandar,
If I remember right the choice that worked best for me was the Adlib sound card. You don't need a slowdown utility as Dosbox does all that for you, you can adjust cpu cyles and such. Just check out the Dosbox readme I think (or maybe their site).
Also, the reason you can't edit is because you're not registered on the forum, if you register you'll have a lot more options.
EDIT: Mighty Midget, just beat me to the reply
