I'm using a Sound Blaster CT2800 on a 386DX-25 system. However, if I use a 16-bit DMA channel for high DMA, I get random garbage output in 16-bit mode.
If I set the high DMA to DMA channel 1 (8-bit), it works fine. This means that the DMA controller has to do two bytes per sample, which is slow, and I want to avoid it.

It works fine on my 486. The weird part is that my CT2291 doesn't have this issue on my 386 at all.
Is this a known issue? Is there anything I can do to make 16-bit DMA work with this card on my 386?
