I've written a program that gets sound data from a Soundblaster
compatible simply by IN and OUT ing to it's I/O addresses, I think
it's called byte mode, or something. Anyway it works on my computer
but I've had a report from someone who says it won't.

He says it works fine without sound in Windows NT, so my prog itself
is sound. But in Win 95 or DOS it locks up. All I do is reset the SB
with the relevant bits to it's reset port, then read the bytes, by
outing to it's command register, then inning from the data register. 

Is there anything strange about PCI sound cards? I try to autodetect
the card by running my reset routine, and if it times out, I know I've
got the wrong address. Or else where should I start looking?
