Start by opening Roon on your Windows or OSX computer, or Roon Remote on your iOS or Android device.
In Settings, click the Audio tab – in the Networked section, you should be able to see your AirPlay devices. Sometimes Roon has trouble discovering AirPlay devices that are sleeping, so if your device isn’t showing up in the list, try waking it up first.
Finally, enable the device (or devices) you want to use, and play some music!
I will add what is not already mentioned above in this post as follows; if anything is still missing please ask.
My LAN is 10.0.0.0/22 I run hypervisors in the 10.0.0.0/24-scope, routers and WiFi accesspoints in 10.0.1.0/24, DHCP clients/workstations in general in 10.0.2.0/24, and servers/static IPs with services in 10.0.3.0/24
The /24 is not subnets, it’s an attempt to describe parts of the /22 network.
My Roon Server and Roon both run on an iMac for now, for initial testing, I will move Roon Server to an LX zone or BHYVE w/some sort of linux once I have the house and garage all figured out.
SkullCandy running Joyent SmartOS as home router 10.0.1.1/22
iMac 27" 10.0.2.100/22
Airport Express( charger like ) 10.0.1.10/22
Airport Express( AppleTV like ) 10.0.1.11/22
AppleTV 4 10.0.1.41/22
AppleTV 4K 10.0.1.42/22
The goal is to move the Roon Server to 10.0.3.100/22 however I’m still questioning which distro is better.
I see that the Core is on the IP range of 10.0.2.X while these devices are on the range of 10.0.1.X. Roon requires all devices to be on the same IP range to properly function. Can you try putting the Airport devices on the sames range as the Core and let us know if that helps?
