Thank you for your help.
 
I've tried both of those links, and they didn't work.  No audio
was recorded.  I can record audio through the GUI audacity,
so I think I have the loopback stuff working.  What is a working
command for recording the audio that is being played over the
PC speakers?

Thank you.
