Thanks!
(Where is this documented? I thought I went through all of the docs...
I must have missed something.)

The apps I need to use still use OSS emulation - will that work?
I'm struggling a bit since sound cards have all sorts of mixers, dsps,
etc. and I need to make sure the soundcard device names don't move
around so the sound comes from the right set of speakers.... The
soundcard/ symlinks are just mnemonics for me so I know what hardware I
am dealing with, but obviously the dsp stuff I need to use.
If I create a name like /dev/dsp01 which has /dev/snd/mixer2, will that
work or will things break in weird ways?
