Hi @Steve_Ackerman,
Thanks for sharing those screenshots. The reason why it is not outputting bit-perfect is because you’re routing the audio through your Mac System Output mixer, which doesn’t communicate directly with the Mojo.
Can you check to see if you are able to enable the Mojo in Roon Settings -> Audio? The screen should look something like this:
Once you enable the Mojo there, you will have to select it from the Zone picker (bottom right-hand corner where it currently says “System Output”).
