Everything was working fine, then all audio output was gone, i can only monitor audio on the analog output connector of the

MADI card, are the optical outputs broken ??? Rme Total Mix shows activity on all channels, and i have green sync all ok, but no audio.

How can i test the MADI card inputs and outputs to verify before i have to send it for repair or purchase a new one.

I have the MADI Hdspe connected to the ADI 8-QS via madi option card..........

Hdspe Madi Out to Adi 8 Madi In,,,Adi 8 Madi Out, back to Hdspe Madi In ?

Or is the problem my Adi 8 Qs hardware ??

No digital activity on Adi 8, only through analog inputs.

All Madi cables have been verified working correctly
