The first time I used ROON I could select an audio output (day, system output,…). Working fine.
Now (second time) there is no audio devices in Settings, Audio.
I’m using a MacBook Pro 2016, 16 Gb memory, Mojave 10.14.3
DAC : Cambridge Audio, Encore MDSD.
Apologies for the continued troubles here. Just to verify, disabling the firewall allowed you to see the devices in Roon but not play to them? Did you receive any errors when trying to play back?
Instead of leaving the firewall disabled, try entering an exception in you firewall and antivirus for Roon and RAATServer. After doing so can you see the devices again?
