With HDA, it plays ok with vsbhda, while with sbemu sound "disappears" after 1/2 second playing ( and video rendering seems to enter a loop, so the demo won't finish ).

However, on another machine with a SB Live card there is some stuttering, compared to what is rendered in a Win9x DOS box. OTOH, with Creative's SBEINIT the demo just crashes.

I remember CauseWay: as default, it prefers VCPI, but if environment variable CAUSEWAY contains DPMI, it changes its opinion.
