I don't have experiences with such a setup. I would avoid using an

Perhaps you should search the web for latency and jitter.

I only read: http://www.rme-audio.de/forum/viewtopic.php?id=7521
They 're just talking about latency, not about jitter. An audio card is
just an IO card, but OTOH we expect precision from pro-audio IO cards.
Keeping in mind that even the combination of mobo, BIOS version and
mounted hardware can cause issues, IMO an adapter could make the
situation more critical.

There perhaps is more to read:

IMO it's not a good idea. When I bought a RME card somebody from LAU or
LAD mentioned that I should keep in mind that even PCI might be dropped
soon. I reconsidered to get a PCI RME and bought a PCIe RME instead,
knowing that it wasn't and still isn't that good supported as PCI models
are.
