According to the pictures you’ve posted, there are no feedback loops present, but since there is a feedback loop, I’d recommend rebooting the Macbook and not using the Aggregate Device for debugging. The Agg Dev’s clock settings further complicate an already complicated setup.
The feedback isn’t coming from a track in Ableton that’s routing DVS 3/4 into DVS 1/2, correct?
With respect to “I also changed the iMac Pro (My main machine) to the same settings, but for some reason my Virtual Soundcard on that Mac does not turn green and I can’t even get to duplicate my tests.”, make sure you have the latest version of Dante Virtual Soundcard on both machines.
