Hi @Arthur_Moseley — Thank you for your report!
To start, may I kindly ask that you please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating. You mention that you are using a switch - Is there any chance it is a managed switch? Can you confirm that the NUC is on the same subnet/in same the IP Range?
When I go back to my original install on my Win10machine, all is OK - all of the audio devices are there.
Is there any difference in the networking setup for the Windows machine? Is it connected to the switch as well? Are you using WiFi?
Regards,
Dylan
