A week ago I installed the HifiBerry Amp2 and it worked like immediately.
Had my Acoustic Research speakers connected to it.
Then I changed the speakers. Switched on the HifiBerry and the system was completely dead. Reinstalled the HifiBerryOS and now it’s alive again. But I don’t see the HifiBerry in the Audio overview. All my other speakers (Sonos) appear nicely.
Here we are, about a month later, and while I hope that things have improved on your end, we’d love to know if we can help at all to make sure you enjoy Roon with your system?
