Sorry, I left out a bit:


pcm.ice1712 {
   type hw
   card 0
}

ctl.ice1712 {
   type hw
   card 0
}

pcm.ice_spdif {
    type plug
    ttable.0.8 1 # S/PDIF left...Delta 9
    ttable.1.9 1 # S/PDIF right...Delta 10
    slave.pcm ice1712
}


A google for "ttable.0.8 revolution", turned up this:

Which may help you.
