Did as advised: commented out the slave.pcm  "digital" and removed the 
comment  for slave.pcm  "dmix-digital".  I then made the change in 
MythTV from "ALSA:digital" to "ALSA:dmix-digital" for the "Audio output 
device".  Rebooted the machine but still no joy.  I'm able to get sound 
out via the analog output if I change "Audio output device" back to 
default of "/dev/dsp".

Please help.  This ALSA to SPDIF is making me going crazy.
