More details about what "doesn't work" means would be helpful. Do you see a SPDIF option in the sound output settings?
In "pavucontrol", it actually does have a listing for the Xonar Sound Card, but only the analog output port is available. In alsamixer, I can press F6 to select sound card, and "Xonar Sound Card" is a selection, but there is no iec958 device.

But it actually is a PCIe x1 card.
If I get into the audio settings in MythTV, it will show the iec958 device, but setting the audio to use it produces no sound.
That is really old information. Probably the reason it's hard to find anything more recent is because generally it all just works.
That's true for stereo sound, but not so true when you try to use surround sound and iec958 devices.
