I use MythMusic with ALSA.

One problem that you may run into is a sample rate problem. Often the 
digital audio output is 48kHz. If the sound is at 48kHz, then there is 
no problem. If the sound is not 48kHz (music is often 44.1kHz), then you 
need to configure ALSA to appropriately. For example, I have the 
following in my /etc/asound.conf file:

pcm.!default {
     type plug
     slave {
         pcm "hw:0,0"
         rate 48000
     }
}

ctl.!default {
     type hw
     card 0
}
