I purchased a SB MP3+ (USB audio device) for my Notebook PC that
includes an optical port. The packaging does not explicitly state that
I can use it to send 5.1 audio to my AC-3 decoder. Before I bought it,
I called Creative Labs tech. and got "weak reassurance" that it will
work (provided my DVD software supports sending to the s/pdif device).
But before I open the box, I thought I'd check with the experts...

The next model up (Audigy 2nx) is promoted as supporting "24-bit/96khz
Surround Sound" and since the cheaper model doesn't say anything but
"Optical S/PDIF Output" does that necessarily mean it won't work?

(I apologize for the clueless nature of this question - I suppose I
could just spend the extra $50 but that, I'm afraid, is exactly what
they want me to do!)
