I have one of these:
Creative Sound Blaster Live! 24-bit External Sound Card

This is the exact one, here:

It's a USB sound card with a free remote control (quite nice and very
small, shirt pocket sized - I use it with a serial receiver).

I have it plugged into a Cyrus AV8 via the optical out. It works
perfectly, out of the box with no effort as well. I get stereo and
Dolby Digital through it from MythTV and stereo from mpd.

I've even modified MythTV to pass DTS through it, a patch I'll tidy up and
submit next month.

My system is FC3, myth 18.1, and I set the audio output device to
'ALSA:hw:1'. Also tick the box for AC3 output. No .asoundrc file (or
whatever it's called) needed. I use the 'Internal' player for mythvideo.
