That got "Unable to find simple control 'IEC958 Playback Switch'", however
# amixer cset name='IEC958 Playback Switch' off

NOW, why my face is red.
Half the problem was solved by System=>Preferences=>Sound and setting 
all the options to ALSA.  Out of the box, some were "nforce" and that 
didn't work.  The only setup that got a positive sound test was the ALSA 
ones.  Mildly curious, since nVidia formerly said their NVSOUND driver 
was OSS; still, whatever works.

BUT, before I got that positive sound test, it helped greatly to plug 
the speakers into "Line-Out" instead of "Line-In."  The color coding 
seemed to match the wrong way.

Thanks for the help.
