With regard to using USB sound devices, and the recently
posted YDL "How to configure audio with an iMic (or similar
device)" on the YDL4.0.1 solutions pages...

And yes, this works.  I found that just modprobe -r'ing the
snd_powrmac module, wothout re-booting, was sufficient to get
the iMic to work.  I have now discovered further that even
removing the module isn't necessary; at least with audacity,
you can leave all sound modules in place and go back and forth
between the internal sound (powerman snapper, in my case) and
the USB device by running alsamixer with the -c flag (alsamixer -c 1)
to enable the iMic, then again without the -c flag to go back
to the internal sound device.
