I am assuming you want all your applications to go to your spdif port.
If so, you need to change asound.conf to this and get rid of everything
else in the file:

pcm.!default {
type plug
slave.pcm "spdif"
}

There are a couple of other configurations that will work as well which I
describe in this wiki.
