OK, so your card only accepts 32-bit samples.

pasuspender -- speaker-test -t wav -c6 -D 'plug:"surround51:1"'

Well, this confirms the issue. Please replace the 
/usr/share/alsa/cards/ICE1712.conf file with the attached one and see if 
it helps. Also please verify the channel positions. Again, a plug will 
be necessary:

pasuspender -- speaker-test -t wav -c8 -D 'plug:"surround71:1"'

Please also verify that the Analog Surround 7.1 profile appears in 
PulseAudio after that (you need to restart PulseAudio: killall 
pulseaudio). If that succeeds, I will post the formal patch to the 
alsa-devel list.

As for the second SPDIF, sorry, I think there is some misunderstanding 
here. According to the reviews, the card has one spdif input and one 
spdif output, both of which are already supported.
