OS X 10.11 Audio Warning

[kraxarn]

When compiling a test app with sfml-audio the following warning is put in the console:
WARNING: 140: This application, or a library it uses, is using the deprecated Carbon Component Manager for hosting Audio Units. Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.
It seems to be an issue with 10.11.x only, but I'm not sure.
I'm running OS X 10.11.6 with Xcode 7.3.1
