Installed Dante card in RML32Ai, why no audio, no audio indicators, No sound?

I installed the Dante Option cards in both of my RML32Ai Mixers, I also have Audinaste Virtual Soundcard AND Audinate Dante Controller installed, all are functionally properly AND BOTH mixers show in the Dante Network and all chaels have been routed. BOTH mixers firmware was updated just 2 weeks ago (before installation of the Dante Cards).

Computer is a Mac Pro 12 Core, 3.0gHz, 64GB Ram, 10TB storage.

After Installing the Dante cards into the RML32Ai Rack Mixers, I no longer get any indication of audio input, the LED indicators are all dark even though i am inputting several chaels of Audio directly to the inputs of both mixers.

What is wrong here? Why no audio at the mixers, no audio in any DAW etc.???
