So "aplay -D plughw:0,2 something.wav" works correctly?

Yes, indeed, I've got sound through the SPDIF output interface

I'm trying to create a mapping in USB-Audio.conf : # If a device does not use the first PCM device for digital data, the

What exactly happens when you try "aplay -D iec958 something.wav"?

No sound through SPDIF output interface :

aplay -D iec958 foo.wav Playing WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
