as i wrote several times 'hw:0,2' is the default. you have to pass the
iec958 capable device to ao_alsa9 like:
mplayer -ao alsa9:hw:0,3 
its hw:0,3 on most sblives. you could have read it while searching the
mplayer-mailinglists or reading the source.
i don't know why 'hw:0,2' is the default, i never really touched this
part of the code, maybe cause the guys iec958 who wrote this part of
the code was on hw:0,2.
i don't know if the iec958 alias is supported on all devices, did you
tested it on other cards too?
i will change it anyway cause it seems that spdif-passthrough is
mostly used in conjunction with a sblive, and the 'iec958'-alias seems
to work there.
at least the whole iec958-initializing part of ao_alsa9 needs to be
reworked, for setting iec958-playback automatically for example. i
can't test it, cause i have no iec958 capable external device so
volunteers needed for this part!
