Mscaler enabled but not selectable as an Output Zone

No I tried clear a bit.
Remote is one thing. My Intel nuc is in the bedroom upstairs connected to Mscaler or Dave .
Im using my old Ipad as remote up there.
But have some other audio devices downstairs where macbook is and will be nic to use it as remote ffor devices downstairs.
Mscaler is other thing not macbook related.
As I wrote Is connected with usb c-usb b to Mscaler ,from Mscaler with BNC digital cables to Chord Dave.
i can see Mscaler in Roon as audio device and can enable it there but cant choose to play with Mscaler its not on the list to choose from devices when press speaker.
