+In addition to the above configuration notes, here are a couple of points about usage 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 and not its default ALSA device. Similarly, by using ALSA's nforce device, mplayer (0.92) 's alsa9 audio driver will also happily generate downmixed stereo S/PDIF output.
+
+However, getting mplayer's ALSA S/PDIF passthrough working is problematic, as its current cvs version has issues with S/PDIF passthrough to ALSA (its hwac3 audio driver doesn't support the commonly deployed ac3 big endian encoding).
+
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].

If you're running Linux 2.6, you will want to use the ohci-hcd [USB] module, in a stanza in modprobe.conf like so:
