This could explain why the sound is choppy for you...
A dma is a direct channel for memory access.

DMA from 0 to 3 have 8 bit access, and
DMA from 4 to 7 have 16 bit acess (these are HDMAs)

Youre using the dma 5 (16 bit) when it should be a 8 bit acess.
Current config for qemu is (in DOS settings) :
SET BLASTER=A220 I5 D1 H5 T5

D1 is dma 1, H5 is for hdma 5.
T5 means Soundblaster 16
