Mine is a "Magic Sound 16".

The gameport should have worked. It does on my system. Does your card not
have a gameport adapter?

Does it work (make ok sound, etc.)

I have one of these cards (which is why we support the IDE and gameports),
but I never got the wss emulation to work. It always died in the ad_probe.

I messed with it in the early days of 1.3B or so, so my experiences then
might be no longer valid. The first thing which needed to be done (which
might have) was to make the ad1848/wss driver take a subrange (it normally
wanted 530/8, but this chip gives 534/4). After that, there's some way to
put the chip in "wss" mode. Normally it expects to be in a "write magic
constant to funky i/o address" mode - something from well before PnP
existed.

I'd love to see it supported, but can't really do much about it other than
testing later on. I can dig up the docs I have for it, though, if you
want.

Take care,

Bill
