I’m using a Synology for running Roon Server and have numerous Airplay devices in the house. I can see the Airplay devices in Roon and select them as endpoints, but no matter the device I hear nothing, despite the graphic in Roon indicating that music is playing!
I tried to put all required information to have RoonServer running on Synology/QNAP. The Airplay/Firewall issue could occur on any machine and I think a general info about firewalls would be more appropiate.
Don’t get me wrong on this, but I think it is not helpful to put issues that can occur with roonserver (on every machine) on a QNAP/Synology Installation blog post as this will divert from the actual topic on how to install and run it on these NAS devices.
