The gui lets me choose hw:0,0 for analog and hw:0,1 for digital. The
string is AD198x instead of iec958.
aplay -L | grep -i iec958 gives me this result though:

I tried 0.8.5 and I got a different error about a buffer underrun, but
the same result over S/PDIF - no sound.
There is a readme included with mplayer, hwac3.txt, containing a lot
of documentation on how they made S/PDIF work, I'm going to start
looking at that. Something about changing AFMT_AC3 channels=1 to
AFMT_S16_LE channels=2 and a non-audio bit somewhere... I am still
a newb at some of this!
