Guess I just gotta RTFM. :) Installing the ALSA config file from here:

http://www.mythtv.org/wiki/Configuring_Digital_Sound

solved my issue. After setting my ~/.mplayer/config as:

ao=alsa:device=mixed-digital

My MP3/PCM video files are now playing over the HDMI interface and I still
have AC3 and DTS pass-through. Joy.

I also installed the second half of the config file on that page that enabled
simultaneous analog and digital output. That solved *another* issue I was
having driving an amplifier for secondary room speakers that needed an analog
source. Double joy.
