Actually I think there is enough information in the original mail for me 
to guess why, but still, please provide the information I have asked 
for. The problem is that your card, which is based on the ICE1712 
chipset, does not expose the 7.1 output and the second spdif output via 
the stock ALSA card file. I.e., the "surround71:1" and "spdif:1,1" 
devices don't exist, and that needs to be fixed in alsa-lib.

You can test the theory by running these two commands:

pasuspender -- speaker-test -t wav -c6 -D surround51:1
pasuspender -- speaker-test -t wav -c8 -D surround71:1

If the theory is correct, the first command should work, and the second 
one should complain (is this actually the case?), and we need to fix 
that in alsa-lib.
