Is your Roon Server an earlier build than version 2.60? If so, then your issue is being caused by an incompatibility between Roon clients version 2.60 and earlier versions of Roon Server. See:

Roon Bridge 2.60 (build 1501) Production with EA Roon Server - Early Access - Roon Labs Community

Either update your Roon Server to version 2.60 (Production) or, if you are running Early Access builds of Roon Server, wait until Roon Labs release a new Early Access version.

Hi @david_swift,

If you’re still encountering issues after ensuring you’re on matching Roon tracks/builds across devices, then try reinstalling RAATServer itself. You can generate a new RAATServer instance on your device by following these instructions. Please be aware that this will reset your Roon Settings → Audio Tab to factory settings, so you’ll want to create a Backup to preserve any essential DSP settings you’ve saved in MUSE.

  • 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

Let us know if this helps.

Also ensure that the Microsoft Defender firewall then still has RAATServer.exe safelisted.

Thanks!
