I hate to say, but it's probably a flaw in the FL audio engine concerning Windows 98's handling of WDM audio. Sorry I can't be any more conclusive, the only machine that I use a kX-powered card with is mine, and it's running Windows 2000
Stick Win2K Pro onto your machine, it'll run on just about any spec box and most probably solve the problem. (sorry, I have to promote my OS of choice

)
