Thanks for testing and I've indeed been careful with testing on all cards. 
The end result doesn't really show it but it's been a rather long series of 
eliminating steps that the original DOS drivers took (with small differences 
between all the types -- but it turned out it seems that most all of it was 
only needed for the "native" SB mode, not WSS).

Should work fine on the 852.

Well, I am, but Jaroslav can have the copyright...

The makefile is wholy trivial. In fact, trivial enough to not even _be_ 
copyrightable in itself and only the ALSA built system as a whole could 
count as copyrightable, I'd say. Keeping that under one single copyright 
might make some things easier.

Or not. I don't care. He can have it ;-)

This is by design. I have a set_mode() function, which takes a "mode" 
argument and the fact that I've defined them to be the command used to 
switch _to_ that mode can be seen just as a convenience thing. And the 
SB8MODE one is retained as documentation (going back to SB8MODE gets you 
floating volumes and the like though -- would need to configure the thing 
completely to be able to do that right, so I don't).

Otherwise, since I was too late for 1.0.15 anyway, things will see a further 
splitup into a library module I guess. My "NX Pro 16" (I38-MMSN803) and 
AZT2320 cards want some of it as well.
