Thank you for your report, @Gerhard_Engmann!
To start, may I kindly ask that you please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Since some days roon stops playing, by the first, sometimes after several songs and then is searching for the core. After a short time roon finds the core, but then looses it again.
To clarify the above - Roon plays several songs just fine and then you lose connection on your remote and playback stops, correct?
- Does playback stop for all audio zones?
- Do you lose connection for all remotes? Have you tried any others?
Since noticing this behavior have you tried rebooting your Core machine, endpoints, remote devices, and networking hardware?
Regards,
Dylan
