Subject2.1.83: Sound, SB16, Modules, MIDI?

I have been wrestling with sound, particularly with trying to get the
stuff to work as a module. The documentation in drivers/sound is mostly
irrelevant and erroneous, and the docs on www.opensound.com were about the
same. I was, however, repeatedly reminded that I could buy the commercial
version which would solve all of my problems. I feel that this is rather
tasteless and am surprised that such commercialisation has been admitted
to the kernel source tree.

Since, for whatever reasons, this is the only sound driver to be found
in the kernel, one must make due. I finally gave up on the documentation
once I realised that, other than suggesting I buy OSS/Linux, it was
useless. I should have resorted to the code first; I quickly found out
that the sb module takes args, and won't work without them. Note
especially the "dma16=5"; without that I got sound, but extremely noisy
and distorted sound.

Adding the following lines to /etc/conf.modules should help users of
SB16 cards who would like to save about 300k of gzipped kernel size
(meaning perhaps a meg of wired ram?) make the thing as a module and
actually have kerneld be able to load it if one, for example, runs
rvplayer, then unload when finished.

alias char-major-14 sb
alias sound sb
options sb io=0x220 irq=7 dma=1 dma16=5 mpu_io=0x330

I still have had no success trying to get MIDI stuff playing. I take the
liberty of including my /dev/sndstat output in case someone else has been
thru this. I think I need a synth device, but none is spontaneosly
generating. I have tried both with and without the MIDI loopback device,
which xconfig informs me has no help available.
