Roon has been working for over a year now, and this error just began. I keep the MacOS, Roon and Tidal all up-to-date. So all versions should be the latest releases.

Hi! Did you try rebooting the Mac and the amp?

#3

And on top of that try another USB cable.

  1. Do you have same problem when used as osx system output?

  2. You can try a Roon bridge device to see if the problem goes away.

  3. Or try to kill core audio

  4. Or try to reset RAAT server

sorry as I do not find the 4000n on google (is it 400s or 400sn?). Or in 4000N, “N” stands for network?

Hi @Mark_Pecoraro,

Do you encounter any errors playing to the system output of the iMac? Recent logs show playback errors on networked endpoints, suggesting there might be a more widespread issue with the output path.

We recommend first refreshing RAATServer on this Core to stabilize conditions:
You can generate a new RAATServer instance on your device by following these instructions, but please be aware that this will reset your Roon Settings → Audio Tab to factory settings and I would advise making a backup of any custom DSP settings you have:

  • Create a Backup of your current Roon database
  • Exit out of Roon
  • Navigate to your Roon’s Database Location
  • Find the folder that says “RAATServer”
  • Rename the “RAATServer” folder to “RAATServer_old”
  • Restart the Roon App to generate a new RAATServer folder

@connor , I followed your instructions, but the problem still exists. In fact, it is now much worse. I can’t get anything to play. I don’t have any other audio issues on my iMac, using the system output or an external USB to integrated amp. All apps/web sites have expected output without issue. Not sure what to do from here. I can use Tidal directly without any problems.

Hi @Mark_Pecoraro,

We’re very sorry for the delayed response. Can you please submit a screenshot of your Device Setup page for this USB device by navigating to Roon → Settings → Audio and clicking on the gear icon? Please expand the menu to “show advanced.”

We’re also curious about any Zone Groups you might have created. Diagnostics indicate two-channel content is reaching your Zone as multichannel - there’s a potential channel assignment issue here.

Also, do you have any DSP engaged for the Gato?
