I have a Lenovo Thinkpad T400 with a mini dock which has SPDIF output. It is running Debian Squeeze.

When I run alsamixer, I can see the soundcard detected is:
Conexant CX20561

When I run aplay -l:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: CONEXANT Analog [CONEXANT Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: Conexant Digital [Conexant Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

However, I can't get it to output through SPDIF. 
I tried:
aplay -Dplug:iec958 /usr/share/sounds/alsa/Front_Center.wav  = no sound

I tried:                                                    
pcm.!default {
type plug
slave {
pcm "front:CARD=Intel"

(restarted alsautils), it still doesn't work.

I tried adding:
options snd-hda-intel model=lenovo-x200
options snd-hda-intel model=lenovo
options snd-hda-intel model=laptop
options snd-hda-intel model=thinkpad
and then alsa force reload
None of these work.

Is there anyway I can get it to output through SPDIF? My other computer that has SPDIF outputs fine using the custom asound.conf so why isn't it working for the lenovo? BTW, I confirmed the SPDIF is not defective  by booting into Windows and testing it.
