What best describes your playback issue?

· My DAC, streamer, or speaker doesn't appear as a Zone in Roon

What type of Zone is affected by this problem?

· *Network Zones* are affected.

How is the affected Zone connected to your RoonServer machine?

· Cable (USB, HDMI, SPDIF, etc.)

Is your device connected directly to the Roon Server via cable or over the network, or is it chained through another device (such as a streamer, Roon Bridge, or Roon Remote)?

· It is connected through a different device (e.g Rasberry Pi)

Does the device play audio from another source when using the same connection?

· The device has no problems with another audio source

Have you checked that Roon is whitelisted in any firewalls?

· I've checked the firewall and the issue remains

Since you are using a network connection to the device, please ensure that your RoonServer is on the same subnet as the device

· My devices are on a single subnet but is not visible to Roon

Do you have a complex network setup?

· Both the device and RoonServer are connecting to a *single router*

Try to disable any additional networking interfaces on your RoonServer machine.

· Disabling network interfaces had no change in behavior

Check to make sure RoonReady mode is selected on the device.

· I've checked this and the issue remains

If the device has multiple output options, do the other options work as expected?

· Only one output type is affected while the other output type works as expected

Is the device using the latest firmware as per the manufacturer?

· Firmware is up-to-date but the issue remains

Do you have an approximate timestamp of when the issue last occurred?

As of MacOS 15.5 update, Meridian Prime does not appear as an endpoint.

Describe your network setup

All relevant devices are on a single router. In ten years of using roon, I have never run into a network issue.

Please read this pinned thread:

Did you try those steps and they didn’t resolve your issue?

To add a bit more detail, my roon setup has been performing near perfectly for the past ten years, but immediately upon updating my Mac to MacOS 15.5, roon on the Mac does not see the Meridian Prime, which is connected to the Mac via USB, as a roon endpoint.

All other endpoints see the roon server, so I’m assuming it is not a server issue.

FYI - I have tried toggling System Settings > Privacy & Security > Local Network > roon setting and then rebooting (as per Carl), but the issue remains.

BlackJack, Thanks for the reference. I had tried that prior to submitting the support ticket.

Hello @Akimo,

Thank you for reaching out to Roon Support.

Please try restarting the Roon Server from the macOS taskbar by following these steps:

  1. Locate the Roon icon in the macOS taskbar (top-right corner of the screen).
  2. Click on the icon to open the Roon Server menu.
  3. Choose “Quit” or “Restart” from the dropdown menu.
  4. Wait a few seconds, then relaunch Roon Server from the Applications folder or Launchpad.

After restarting, please check if the issue persists and let us know the result.

If you encounter any issues during this process, feel free to share more details — we’re here to help

@vadim,

Thanks for the troubleshooting steps.

I think I may have discovered the problem. The Prime routes its USB through an external power supply box.

When I bypass it, and connect USB directly to the Prime, the issue goes away. Looks like it’s a HW problem.

Please close this ticket.
