Okay, this is driving me nuts. Black screen, fans ramp up, and about five seconds later Windows comes back like nothing happened. Then this pops up:

USB Audio Device Properties
Device status:
This device cannot start. (Code 10)
{Operation Failed}
The requested operation was unsuccessful.
Its always while alt-tabbing out of a fullscreen game. My small form factor PC is not overclocked and temps look normal in the vendor overlay. The only change i can point to is the Radeon Crimson Edition Graphics Driver 17.4.2 Hotfix update from AMD. Ive already restarted a dozen times, obviously. Is there a log somewhere that tells me what actually timed out, or am i stuck guessing?
