Hello @Antonius_Schuh,

Thanks for contacting support, I’d be happy to assist here. When were these devices previously listed, before you updated to Mojave or what other changes have you made since they stopped appearing? Please let me know the model/manufacturer of your router, and switches, powerline adapters, range extenders, ect.

Can you post a screenshot of your Roon Settings -> Audio Tab? It should look something like this:

I would also reboot your Core & all networking gear and check your Mac’s firewall settings using these instructions and confirm that both Roon and RAAT are listed as exceptions. If you have any other firewall applications running such as “Little Snitch” or “Bullguard” I would make sure that Roon and RAAT are set as exceptions there as well.

Please let me know the above information when possible and we can continue from there.

Thanks,
Noris
