Neither do I. =)

Looking at the datasheets and schematics, it looks like the CS4630 uses
AC97 codecs to actually process and output it's iec958 frames. I could
easily be wrong, but the schematics for the CS4630-CM don't show the
circuitry necessary to power and control an iec958 line. It shows a pin,
which I assume links to the codec (in my case, a CS4297A). Is there
a datasheet that could show me what you mean?

No, I haven't changed a thing.

Strange. Well, if it _were_ the case that my card is using a CS4297A
for
digital output, do you think that would cause this?
