DDP Player Audio Output


I think I’m putting this in roughly the right place as I couldn’t find a specific DDP player category!
In my studio my main output to monitors is Dante Virtual Soundcard (DVS) 31-32, however DDP player will only output down lines 1-2. I can’t seem to find any way to change this, anybody know if there is a reason for this, or if it’s a bug? In Audio MIDI Setup on macOS the main outputs for DVS are set to be 31-32.

Thanks in advance!
