I don't have a MAC so this may be different but to get sound working on 
my system I did the following:
1) remove or rename the two alsa config files (asound.conf and .asoundrc)
2) some people have to uninstall pulse audio.  I think this is with Fedora.
3) Sound ALSA:default
4) Passthrough ALSA:spdif
5) check Stereo (not 5.1)
6) turn on iec958 in alsamixer


In my experience, if you try and follow any wiki and set up asound.conf, 
you are dead.  The defaults are used if there is no config file and they 
work great.
