Sorry, I missed part of your question, once you've established that the usb
speakers are working, you may use the cd player module in xmms to play a cd.
xmms allows you to set the audio device in it's preferences. I found it to
be a bit counter-intuitive, using the file selector to select audio tracks
from a cd. There may be another program that lets you set the audio device,
but in the past when I knew that I did not want to use the built in audio, I
disabled it in the bios or removed it from my kernel config file, thereby
making uaudio0 the only audio device. Yeah, I know it's a hack.
