Devialet not recognised on Audirvana or Airfoil

[intrigued]

I use Audirvana and Airfoil for my streaming.  I acquired two Phantom I speakers two days' ago but neither of these programs recognise them. However, the speakers are strangely recognised by mConnect Lite (that is the only app which recognises the Phantoms). I've restarted my Mac laptop but nothing has changed.

Please advise with any ideas how to get Audirvana & Airfoil to recognise my new speakers.  Thanks for your time.
