Hi @Martin_Joyce ----- Thank you for the report and my apologies for any confusion on my part. I just want to make sure I am conceptualizing what is going on here correctly.
You have two PCs and some Android devices acting as remotes controlling your SonicOrbiter running RoonServer. You’ve been able to get PC#2 operational based on the advice provided by other users, however there is a DAC mounted to this computer via USB that Roon is not recognizing, correct? Furthermore, PC#2 is able to recognize the DAC(s) mounted to PC#1, correct?
Martin, I greatly appreciate the clarification and would kindly like to to ask you to lay out the details of your setup as seen here. I want to understand exactly what you are working with, how the devices are being used (i.e remotes etc), and the functionality you are trying to achieve with this setup.
