I have a couple of jumperless Creative SB 16's ISA. A DOS configuration program sets all the interrupts and settings for it. They worked in DOS mame just fine for me in 2 PCs. But my final PC they didn't work well with - they would make a constant clicking noise whenever 16 bit music would play. I know it was some kind of compatibility with that PC because both of them showed the same problem.
If you are interested in one, let me know, I'd be happy to sell one of them.
