And yet the SPDIF in works fine in spite of the input error message, 
it's just the SPDIF out that doesn't work.

I don't know if it counts for anything, but the card shows up correctly 
as M-Audio Audiophile 24/96 in Qjackctl.

When I tried modprobe -r it said "FATAL: Module snd_ice1712 is in use" 
but adding with the model type worked fine. I didn't have Mudita running 
whilst doing either of these.

I found the alsa-base.conf file, but I wouldn't know what to start 
fiddling with. There's no mention in there of snd_ice1712 though, dunno 
whether that's indicative of anything.

Many thanks
