Re: [Alsa-user] Re: emu10k1, sound blaster audigy two zs and digital output

"iec958 optical raw" - is switched on, because ac3 data have to pass 
through DSP unchanged.

try to play normal stereo wav file with aplay ("iec958 optical raw" will 
be turned on and you will be not able to change volume - set lower 
volume on your receiver, because otherways it will be high)

aplay -D spdif some.wav

You should be able to hear sound. If this works then problem can be, 
your audigy is not correctly identified (some have bug in ac3 passtrough).

What alsa version do you use (cat /proc/asound/version)?
