You seem to have your IEC958 turned down to 0 in the mixer control:

I have mine (NF3) as:

Simple mixer control 'IEC958 Playback AC97-SPSA',0
  Capabilities: volume volume-joined
  Playback channels: Mono
  Capture channels: Mono
  Limits: 0 - 3
  Mono: 3 [100%]

I need it adjusted to maximum (3) in order to get any audio via SPDIF.
Make this adjustment and see if it works.
