I have been using Roon on a Ubuntu Server 16.04 for year without major glitches. I have made a new install (ubuntu server 20.04) on the same machine (just changed the SSD) and Roon now does not see the Bluesound node2 and the Bluesound Pulse Mini. I can use the speaker and DAC through the BluOS controler but not through Roon.
When I installed Roon, everything was cheked OK.
I have checked Roon > Settings > Audio…
What am I doing wrong???
Core Machine
Intel Nuc i3 with Ubuntu Server 20.04 and latest Roon server.
When I de-authorize the NUC server and authorize Roon on my Macbook, then the Bluesound devices appears. But when I go back to authorize the Nuc, they are not there.
Is the Ubuntu machine behind the router/firewall?
Do you need the Ubuntu machine to have its own firewall rule set?
I run my Ubuntu server 20.04.2 LTS CORE behind a router that handles the traffic and firewall policies.
