Well, my results from this morning:

Changing the default output device from ALSA:Default to ALSA:plug:iec958 
worked.  I have sound on all stations and mythmusic going to /dev/dsp is 
working fine as well (I may try pointing music to the plug:iec958 for 
giggles to avoid that damned Optical Raw setting on the SB Live card).

As for the idea of an ALSA config problem:  I did look at that 
possibility as well, but considering I'm running the asound.conf that is 
listed in the wiki with a SB Live 5.1, I'm having problems seeing it as 
ALSA having the problem and not just Myth.

I'm not claiming to know everything about how Myth interacts with ALSA, 
and I have been wrong before, but when I'm using pretty much the 
'standard' for Myth and digital sound output, well....  :-)
