I think a few people here said they were using one of the 192's. I recently got one and installed the latest drivers, 3.80. While playing back the timeline it will sometimes stutter through audio crossfades, and almost appear to get stuck there for a few seconds, looping over the same few frames several times before continuing.
I'm working on an hour+ project and it only seems to happen if I've been playing back for several minutes. I can usually fix it just by stopping and re-starting playback, but that's a nuisance I'd like to avoid if possible.
This happens whether I've set Vegas to use the Windows Classic Driver or Microsoft Sound Mapper. It sure was cool, though, to see Vegas add the little router button to the master bus so with a click I can be outputting either to my monitors or nearby TV.
