This won't be of much use to OP, but fwiw to anyone else who happens upon this thread, it might be a good idea to hold off on 1803 for as long as possible. I have a friend here in town that builds systems for audio, and he's run into a few hiccups of his own.

There's also a (generally) great thread on Win10 over at GS, where one of the audio guys from Microsoft regularly chimes in, and there seem to be several reports of flaky behavior with 1803 over there as well. Be warned though - right now the thread is mostly 3 or 4 knuckleheads yelling at each other over forced updates.
