I noticed that too.
That (woefully-named) hiFace thing K3cT pointed out actually looks like it might be interesting, though. They've written the custom drivers necessary to get 24/192 sample rates (including on Atom-based platforms) and seem to have thought seriously about the (potential) jitter issue. Although, of course, I don't actually have the technical competence to tell if their claims are gibberish or not.
