How about a USB soundcard with digital audio out? Would that solve your
problem? I have a small Turtle Beach USB sound card that has optical out.
I got it for a different purpose (my onboard optical out was not supported
in Linux). It's an older card (about 5 years old) but perhaps there is a
newer equivalent. It works like a champ. It was quite inexpensive.
