Jessariah,
I used to have the same problem with the Delta 44 and Win98SE. It drove me insane for a couple of months before i finally tried an older driver. The driver you need is del22.27.exe Go to the M-Audio and download it. I'm almost possitive this will solve your problem.

P.S.- another option is to upgrade to XP, that's what i run with now, the 44 and the OS work great together.
