* NVidia CK804 (integrated into the motherboard MSI K8N Neo4 Platinum)

aplay -l:

card 0: CK804 [NVidia CK804], device 0: Intel ICH [NVidia CK804]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: CK804 [NVidia CK804], device 2: Intel ICH - IEC958 [NVidia
CK804 - IEC958]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

* Alsa drivers 1.0.8-7 (= latest stable version on Debian Sarge)
[2.6.11 kernel, Debian sarge]

I used to have a wav-file which played 5.1 audio using these drivers,
but have misplaced it. But I think it was encoded into DTS 96/24 (96kHz,
24bit samples) which is IMHO not supported by any plugin. This means
that the connection probably works, but the internal hardware Dolby
Digital decoder is not happy with the format, right?
