Here's my setup and what's currently working.

Enemy Territory Quake Wars worked but crashed after a couple of minutes. 
Graphics card is new so can't be sure what happened.

If I set Gnome to use OSS I can get sound from Rhythmbox.

Sorry to tag this on to the end of this message, the problems below are 
likely of my own causing rather than the sbxfi driver...

I'm investigating why when I select alsa or pulse in Gnome I get an 
error on clicking the test button.
"audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! 
gconfaudiosink: Could not open audio device for playback."
Selecting OSS and clicking test I hear the sine wave.
But I cannot hear any desktop effect noises or the system bell.
Same issue with KDE. I hear the log on tune but nothing else from the 
desktop itself.
Possibly my machine is just too messed up and needs a re-install, it's 
been upgraded continuously from around FC3 and could do with an overhaul.

Regards, Jason
