Well, running all controls up on alsamixer technically works. Which 
admittedly surprised me.

Of course, "works" could be a little misleading. Under Knoppix, the output 
to the speakers is loud enough to hear from a distance of 2-3 feet. Not 
load, but audible. Under FC4, with everything cranked up, pick the little 
speakers up, and place them around your head like head phones to hear the 
test tone. None too load either, but technically the software is working 
with the hardware, and I can arrainge to use amplified speakers if need 
be. Now to investigate further the cd player.

Thanks to all for the bandwidth, and thanks to Aaron for the prod in a 
usable direction.
