I'm unable to enable any local audio devices

Hello @Michael_Braun

Since you’re running macOS, the behavior you’re seeing is consistent with the newer, stricter Local Network permission controls in the recent macOS releases.

Please try the following steps:

  1. Open macOS System Settings → Privacy & Security → Local Network
  2. Make sure Roon and Roon Server are both enabled
  3. Even if they are already enabled, please toggle them off and back on
  4. Fully quit Roon Server from the macOS menu bar / task bar
  5. Reboot your Mac
  6. After reboot, launch Roon again and check if the devices is avaliable again.

Once these permissions are refreshed and the system restarted, your audio devices should reappear.

Please let us know if the issue persists after these steps, and we’ll continue from there.

Hello @Michael_Braun,

Just checking in on this. Have you had a chance to review the macOS Local Network permissions for both Roon and Roon Server, toggle them off and back on, then fully quit Roon Server and reboot the Mac? If you tried those steps already, let us know whether the audio devices came back after the restart, thanks.
