:)

The s/pdif inputs are 9 and 10 normally (on the ice1712). Audacity will 
only record those if you record 10 tracks at a time. You can then split 
them into single tracks and then delete unused tracks... The mixer will 
not let you change this. If you are using pavucontrol, you can try 
setting the device to s/pdif only in the configuration tab... I have the 
devices turned off in pluse on my system so I can't check, I run pulse 
into jack all the time. Anyway look in the configuation tab for your 
device.

Or you can start Jackd first and then set audacity to talk to jack instead 
of alsa or pulse. You can use qjackctl to connect audacity to channel 9 
for recording. To see levels hit pause and record... infact you will have 
to do this before you connect ports with qjackctl.

This is why I would use pulse bridged to jackd so I can connect pulse to 
the right ports ahead of time. Then if audacity is using pulse it will 
"just work" (for me anyway).
