In addition to the above configuration notes, here are a few usage notes to keep in mind:
With the above /etc/asound.conf xmms (1.2.8) will happily use its alsa-xmms (0.9.12) output plugin when its configured to use the "nforce" device instead of its default ALSA device. Similarly, by using the alsa9:nforce audio device mplayer (0.92) will also happily generate downmixed stereo S/PDIF output.

-What about six channel output? While here the alsa nforce device has its problems, the emulated OSS devices are beautifully functional. Here is an example mplayer invocation that sends 6 channel audio to the S/PDIF output:
-<verbatim>
-mplayer -ao oss:/dev/dsp -channels 6 dvd://1
-</verbatim>
-The xine player can similarly provides 6 channel output via its OSS audio driver.
These nforce2 S/PDIF ALSA usage notes are current as of ALSA 1.0.2 (circa Feb/2004). The above config was tested with an unpatched linux kernel 2.6.3 (alsa-driver 1.0.2c) on an ABIT NF7-S rev2 optically S/PDIF connected to a Cambridge Sound Works DTT3500 Digital Home Speaker System.
I found these invaluable files within ALSA's [Documentation|http://cvs.sourceforge.net/viewcvs.py/alsa/alsa-kernel/Documentation/#dirlist] directory: [ALSA-Configuration.txt|http://cvs.sourceforge.net/viewcvs.py/alsa/alsa-kernel/Documentation/ALSA-Configuration.txt?view=markup] and [OSS-Emulation.txt|http://cvs.sourceforge.net/viewcvs.py/alsa/alsa-kernel/Documentation/OSS-Emulation.txt?view=markup].
