You da man! What I have now is this... To my /etc/asound.conf I added:

pcm.ice_spdif {
    type plug
    ttable.0.8 1
    ttable.1.9 1
*    slave.pcm digital*
}

And I also dropped that ao line in my mplayer.conf file and now mplayer 
acts like it's playing the audio fine although it doesn't actually 
output audio to my speakers. Then, in my MythTV terminal using 
"mythfrontend -v audio" is throws 1/2 a million "waiting for space on 
soundcard" messages when watching a DVD which are similar to the 
messages it logs when I can actually hear sound on 2 channels... so I 
think that you have me pointed in the right direction, but could those 
ttable lines be different for my Revolution 5.1 card? Do you happen to 
know where I might be able to research that so I can play with them on 
my card?
