Sound Demo not working

Hello!
I’m trying to run the sound demo on Psychopy, but I receive the following warning message, and no sound outcome at all.

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.

Does anyone know how to handle this? Should I update my Psychopy (v. 1.85.1) in a OS X El Capitan 10.11.6?

Thanks!
