I haven't had any problems with my UX1 ever since I disabled it from being default audio playback source in Windows, which would be quite stupid anyway in my use, since I want it to assist me with playing and recording, not playing random Windows bleeps. I'm only using it with ASIO. The random sounds and generic multimedia goes through on-board soundcard.
I have the latest drivers installed, POD Farm, Monkey, all of it. No problems so far. Apparently ASIO model doesn't change much, or they take car of backwards compatibility.
