Problems with digital input of ESI Juli@ xte PCI Soundcard

I've got an ESI Juli@ xte PCI Soundcard and want to use it on Ubuntu 12.04 Server. It's going to be a capture device only. It's used in a small free radio station. I want to use two analog inputs to capture the live radio program and the digital spdif (coaxial) in for streaming via darkice (icecast2 client) at the same time.

I got the analog inputs working well with arecord, but I'don't have a clue how to use the coaxial spdif in for the stream at the same time. I tried different audio device settings, to stream the digital in, but with no success (plughw:0,1, iec958:0,0, dsnoop, dmix...).

Does anybody know how to detect the right device adress? Here are some more details:
