Hi @Bruce_Votipka,
This is Noris from Roon Labs Support here, thanks for your patience while your case reached my queue!
As @jb76 mentioned, on the Squeezebox devices themselves you’ll need to go to My Music → Switch Library and point the Squeezebox devices to the Roon Core. Then you should be able to enable and get them working in Roon Settings → Audio.
If you have any issues after pointing them to the Roon Core, please just let me know and I can assist further, thanks!
