Everything worked fine until I upgraded to Roon 2.0. Now, none of my streamers are seen by Roon. I tried rebooting the Mac mini that houses Roon 2.0 and each of the streamers. I use a combination of Volumio OS, Roipieee and Hifiberry. They all worked fine yesterday. Today they do not.
Roon does NOT see any of them under Settings, Audio, so this is not a simple Enable situation.
Have you restarted your network? Power down everything, and then bring up the modem / router. When this is operating (it may take a few minutes), turn on any switches and Wi-fi hotspots. Then turn on your core, followed by endpoints.
I upgraded RoonBridge on my laptop. I have never installed it directly on any of the streamers. I merely installed the OS for the Pi – HifiBerry, Ropiee, and Volumio (which requires a Roon plugin).
I’m running the 20220826 update with hifiberry and it’s working with 2.0.
This update was a bit stubborn and I had to force it manually a few times to get it to take.
Maybe check if yours is updated?
