Sound Demo Warning message

Hi there! I’m trying to implement the sound demo to play some music tracks for an experiment.
However, when I run the demo (without changing anything) I get this message:

Using pygame(with None) for sounds
2018-02-14 14:12:03.459 python[4914:354430] 14:12:03.459 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.
done

Any ideas how to make it work?
