i don't have an spdif source, so i can't test, but it used to work on my 
sblive when i set the capture flag in alsamixer on "IEC958 Coaxial" 
*and* the "capture" channel. there is also a capture gain next to it, i 
don't know which position is "neutral", you should probably ask on 
alsa-dev...

best,

jörn
