Description Of Issue
I have lost all output from Roon, both to my UltraRendu and my core MacBook Pro.

Roon is up and running, I have updated and re-booted my Rendu, but neither devices now show as recognized audio outputs on my Roon Manage Audio Devices tab when clicked.

How do I enable them again?

Thanks so much,


Do any devices show up when you navigate to Settings | Audio? Can you share a screenshot of this window?

I had this once, using my microrendu. Simple re-booting did not help. I had to disconnect the power to the microrendu, switch on my dac (connected to the microrendu) and then re-connect and re-boot the microrendu.
