Before you buy a USB sound device, you may want to consider another option: 
Many motherboards have SPDIF connectors on their motherboards. You can buy or 
build a simple bracket adapter that provides coaxial and/or optical outputs 
from these motherboard connectors. Examples include:

I've got an adapter from the latter of those sources and it works fine with my 
motherboard (a Biostar, IIRC). Check your manual to see if you've got the 
necessary connector. In some cases it may be necessary to move some wires 
around, since the pin ordering isn't standardized, but that's a minor task. 
Of course, you'll also need to have fully functional audio drivers for SPDIF 
output.

Instructions for building your own are on the MythTV wiki:

IMHO, building your own is much more hassle than it's worth, unless you just 
enjoy that sort of thing.
