Same for me.
I don’t see:
Sonos Bean (visible and usable via direct AirPlay on all devices; not visible in Roon settings)
RoopieXL via Airplay (as above; Roon version is visible and I can play there; not visible in Roon settings)
Macbook Pro speakers (usage in MacOS; visible in Roon settings)
Sonata Hd Pro connected to Macbook (also usable when using directly from MacOS; visible in Roon settings)
My core is running on Synology. Sonos & Roopie are on the network connected via WiFi and Macbook is connected via ethernet. Rebooting Synology did nothing. All devices were visible & working on 1.7.
