I assume you are referring to you Audio/Midi Drivers. From my experience it is not unusual for these to "disappear" despite the fact that they still are found in hardware manager. I have always blamed this on Win 10 upgrades. Simple fix - generally, just reinstall them. BIAB should find them once they are re-installed and system is restarted. Good Luck.
