Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
AppleTV 4k (ethernet>Netgear>Velop>Netgear>Fios router; AppleTV4k connected to Denon AVRx3500 via HDMI and to network via ethernet; Apple TV (older version, connected to Velop Node via ethernet and Toslink [in another system]), Oppo 203 DVD connected to network via ethernet used as a freestanding CD player and Roon endpoint
Description Of Issue
Roon doesn’t see the AppleTV 4K (it hasn’t since I bought it…a few days ago). Roon does see the older Apple TV. It also sees the Oppo and plays over the Denon AVR via Airplay.
It is OS 13.3 (17K449). The older ATV (Model A1469) is using OS 7.4 (8081). They’re both connected via Ethernet. However, in order to look up the OS on the older ATV (it wasn’t hooked up to a monitor), I swapped out the newer ATV4k and put the older ATV in its place (so the connection to the ATV was now IDENTICAL to how the ATV4k had been connected, including being connected to the Denon AVR via HDMI). I then checked to see if Roon could still find the older ATV. It could.
