After reading some more man pages, I am still stumped but can better
phrase my question:
how do I set dsp0.0 as the default OUPUT and dsp1.1 as the default INPUT?
...
Audacity will be able to specify a different dsp device for the
recording and playback device via the "Audacity Preferences" panel
("Edit" -> "Preferences" -> "Audio I/O"); e.g. /dev/dsp0 for playback,
and /dev/dsp1 for recording.
Have you tried such configulation?

No luck. I only see '/dev/dsp'. It seems that dsp likes to automatically do stuff, but is not
smart enough to always do the right thing.
OK. My understanding is:
* There is /dev/dsp0 which corresponds to pcm0 (snd_hda).
* /dev/dsp and /dev/dsp0 are the same. e.g.:
$ ls -l /dev/dsp /dev/dsp0
crw-rw-rw- 1 root wheel 0, 83 Dec 14 20:55 /dev/dsp
crw-rw-rw- 1 root wheel 0, 83 Dec 14 20:55 /dev/dsp0
$
* There is no /dev/dsp1. But there is /dev/dsp1.1 which corresponds
to pcm1 (snd_uaudio).
If these are correct, will you try to make a symlink /dev/dsp1 which
points to /dev/dsp1.1 via devfs.conf(5)? i.e. Add the following line
to /etc/devfs.conf and then reboot the system:
link dsp1.1 dsp1
I entered these lines:
# attempt to override the dsp0 input with the dsp1 input... doesn't work
link dsp1.1 dsp0.1
# this didn't do anything
link dsp1.1 dsp1
# this works... wanted to make sure I could do something. :)
link dsp1.1 microphone
and ran
/etc/rc.d/devfs restart
# ll /dev/ | grep dsp
