I've been trying to get speakfreely to run under FreeBSD 4.5 and/or 4.6 
release without luck.  Speakfreely receives and plays audio and sends audio 
from a file without problem.  But when I try to use the microphone I get 95% 
distortion.

I *think* the problem is associated with /dev/audio.  If I 'cat /dev/dsp > 
/dev/dsp' the echo sounds fine.  When I attempt the same with /dev/audio I 
hear the same distored echo as when I run speak freely.

When I try to capture directly to a file I get the following:

--- snip ---

I get the same results under 4.6 except that the audio device stays busy 
after the cat so I get only once try per boot.

Anyone have any ideas ?  I *know* I've run speakfreely on FreeBSD in the 
past, but I don't recall what release or exactly what hardware I was 
running.
