Hi @Rugby !
Thanks for your help. I have already tried that but no luck. As you can see, my three devices that are currently connected appear in the “About” section:
What worries me is that Roon seems to be confusing the audio devices in my core with the ones in my Windows PC, and because of that I’m not able to enable the audio devices in the Windows 10 machine. It does not seem to be a firewall related problem because I have disabled the firewalls in both the Debian machine (core) and my Windows 10 PC. I think the problem is located in the Windows 10 PC because my Macbook Pro works well.
Any help? Thanks again.
