Perhaps I'm going about this the wrong way (if so, please tell me), but...
My X-Fi card is now working with the new driver. I am connected to my
amplifier via a fiber optic cable. Sending standard two-channel audio
to the "front" alsa plug gets directed to the spdif output and sounds
great. But I want to have my full surround active - particularly for
movies already encoded with dts and/or ac-3.
Thus far, I have not been able to get mplayer to send digital audio - I
either get mplayer errors or silence. Once, and only once, I got xbmc
to work with digital settings - never since. So I know it SHOULD be
possible - I'm just missing something.
Is anyone getting this to work?

Do I need to specially configure ALSA is any fashion to make this work? Do I need to use the iecset tool?
I'm using Kubuntu Karmic, running a 2.6.31 kernel, if that makes any difference.

You need to configure the application playing audio to use AC3 passthrough, which will simply send AC3 directly from your app via optical to your amplifier.
