No factory registered for id CFUUID

I get this error in the console every time I run my app:

[plugin] AddInstanceForFactory: No factory registered for id <CFUUID 0x600001d04c80> F8BB1C28-BAE8-11D6-9C31-00039315CD46

It's SUPER-annoying. While I have audio in my app, the app opens to a view controller with no audio. Audio and Recording both work in my app; zero issues running anything in the app-- just this console error.

Everyone seems to think this error relates to audio, and altho that's likely, why would I get the error before any audio is used, or any viewController with audio capabilities is even called?
