We have a winner! Commenting out the Option "UseEDID" "False" line allows 
sound to flow out the HDMI port. Jim, Ryan Seacrest will be at your house 
shortly with an oversize novelty check and a van full of balloons. Many thanks.

MythTV is working with the "ALSA:plughw:0,3" syntax.
Mplayer is working with "ao=alsa:device=hw=0.3" in the config file.

Now I get to figure out the whole audio encoding pass-through thing. My first 
couple of tries at recordings gave me static. After UN-checking the 
passthrough options in Myth, the sound came back. Obviously, this Asus 
computer monitor doesn't offer AC3 or DTS decoding. I suspect that once I get 
this plugged into the flat screen TV, I'll be able to turn those options back on.

Many thanks to one and all!
