Hi,
I have had Roon Server running on an Ubuntu box with my Windows 7 PC setup as a remote for the last few months. Everything has worked flawlessly until just a couple days ago. What has changed is that now, when I start Roon on the PC I am able to see the other outputs on my network (a Raspberry PI and Macbook Pro) with their audio outputs, but I am not able to see the audio outputs on the PC (which were there before). Playback and control is fine on the other outputs. I have rebooted the PC a couple of times and tried with firewall both on and off.
Any ideas on what might be happening?
