? PC/Cardbus (removeable) card ?
Some audio equipment has SPDIF for digital i/o because analog to
digital conversion losses some signal quality. I have an external
cdrw drive with those outputs but no computer with the inputs;
nevertheless I can play cd direct to digital via firewire. (my old
computers are the kinds with cheating analog cables between their
builtin optical drives and their motherboards, that is exactly the
kind of loss I just mentioned (D->A->D).
If you have a laptop rather than a desktop, its hard to tell whether
you have the cheat or a real digital cd player, unless perhaps this is
it (I don't have your powerbook to see).
It would be easier to relate to what you see there if you could give
the full description in context, did this info come from
AppleSystemProfiler, or did you read it off the piece of equipment, or
what ?
