I am trying to output the audio from my 1824c into another device but neither the optical connection nor the s/pdif is sending a signal. When I open Universal Control there are no levels showing in the S/PDIF or any of the ADATs. I've gone into the Logic Audio Setting and selected "S/PDIF Out Left/Right" as the output but there still are no levels showing under S/PDIF in Universal Control. Levels show up only on DAW 1, 9 and 10.
