What I'm really asking is:
1. Though I did have HDMI audio working immediately after my Mythbuntu
install, why did it suddenly go away? I swear I touched no audio
settings after the post-installation setup, though I do faithfully apply
updates.
2. Why did none of my hacking on /etc/asound.conf and ~/.asoundrc manage
to restore HDMI audio?
3. Why did HDMI mixed audio "magically" return after wiping the ALSA
config files?
4. Where does Ubuntu/Mythbuntu store the settings that caused HDMI
output with mixing to work?
To quote the King of Siam: "It is a puzzlement!"
