In sound/isa/cmi8330.c, the ENABLE_SB_MIXER code is currently never
used.
What's the story behind this?
Should ENABLE_SB_MIXER be enabled?
Or the code be removed?

CMI8330 has a dual interface for SB and Adlib modes. The mixer can
also behave differently according to the mode. The current code has
mixer elements corresponding to both modes.
However, these mixer elements _seem_ to interactive with each other,
and cannot be controlled individually. That's why ENABLE_SB_MIXER is
disabled. I cannot check this issue any longer since the test board
got broken long time ago...
I don't think we would get many gain by changing this old code.
(and the relevant part isn't so big.)
Let's keep as it is.

CMI8330 (and also CMI8329) appears like SB16 and WSS

The mixer is a bit weird - and probably different between CMI8329 and CMI8330.
At least on my CMI8329A, the master volume does not work. And there are also
some problems with PCM volume - I can decrease it in alsamixer but not
increase - but it works both ways in XMMS...
I have also some boards with integrated CMI8330 - so I might test it
sometimes.
