uaudio0 -> audacity not recording

[Russell L. Carter]

Greetings,
I am going to take a stab at this again before giving up.
On 10/stable, I have a Behringer UCA202 that plays fine.

When I play a vinyl record through the soundcard the output is
fine. Every other source I've tried plays fine too.

When I start up audacity, I see displayed:

OSS, /dev/dsp, 2(Stereo) Recording Channels, /dev/dsp

When I click on the monitor pane, I get level bars corresponding to
the monitor levels I'm hearing.  I hit the record button and I seem to
be seeing sensible record levels.  But when I hit the (re)play
button, I just hear a bunch of garbled noise, not very loud.  A
curiosity to me, but perhaps unimportant is that the audacity displays
/dev/dsp, but only /dev/dsp0.0 exists.

I build audacity using poudriere, and all options are set except
for lame and debug.

Could be a rookie mistake with audacity, or freebsd recording, or
something else.  Any ideas?  This setup works fine on linux.

Thanks,
Russell
