No audio devices found: I came back home from a trip to find that there had been a power cut. I’ve managed to reset everything but Roon will not find the speakers throughout my house, though Spotify has no problem doing so.
I’ve rebooted everything in sight, several times. I’ve deleted and reinstalled Roon on my Mac mini, which I use as a server.
Welcome to the forum! Can you please navigate to macOS System Settings > Privacy & Security > Local Network , and make sure Roon is allowed. If it is already enabled, toggle it off and on again. Then reboot your Mac, and see if the same issue persists.
Does the issue happen with local library music, streaming service music, or both?
· *Both streaming and local* *library* music are affected.
Do you encounter any playback errors with the "System Output" Zone?
· The System Output has *no problem*, it's only my other Zone.
How is the affected Zone connected to your RoonServer machine?
· Network - Ethernet
Which network audio protocol is the Zone using with Roon?
· RoonReady
Does the device show up at all in Roon Settings -> Audio?
· No, it does not show up there
Does the device play audio from another source when using the same connection?
· The device has no problems with another audio source
Have you checked that Roon is whitelisted in any firewalls?
· I've checked the firewall and the issue remains
If the device has multiple output options, do the other options work as expected?
· Multiple output types are affected
Is the device using the latest firmware as per the manufacturer?
· Firmware is up-to-date but the issue remains
Do you have an approximate timestamp of when the issue last occurred?
· This is the same issue as before: No audio devices found after power cut (ref#MCW5G0). Your prior advice made no difference whatsoever. I need a human to help me or this system is never going to work again.
What are the make and model of the affected audio device(s) and the connection type?
· Araknis switch and router
Describe the issue
No audio zones found
Describe your network setup
This is beyond my technical ability. I have a professionally installed home network.
What is the OS of your Mac running the RoonServer?
And can you describe what the other zones are that you are not able to play to?
There can be several reasons that your Roon Server cannot see remote zones. The fact that you can play to something local suggests it is network based, however.
If you are running Sequoia then there is a new MAC OS “feature” which is causing a RoonServer to loose audio devices. The fix for this is what Noris suggested that you do. However, that fix only works until the unit reboots and then you need to redo it. So, if you are running Sequoia on that PC, try Noris’ suggestion again and see if it makes a difference.
Again, make sure the Mac’s firewall has excemptions for RAATserver, RoonServer, and/or RoonAppliance as appropriate.
Also, verify that the IP addresses of the Mac Server and the remote zones are all in the same subnet. i.e the first three number groups are identical.
You don’t mention the model version of the Araknis, but, I am going to assume that it is one of the “managed” switches. Managed switches have all sorts of options that can cause Roon problems on a network, which is why the suggestion under the official Roon networking FAQ not really use them, see here https://help.roonlabs.com/portal/en/kb/articles/networking-best-practices#Managed_Switches. If all that is not understandable to you, you should have your networking guy read it.
One of the issues is that it takes networking knowledge to make sure everything is working right with a managed switch. Great if you know it, Not so great if you don’t. The power outage you mentioned could have changed some default setting on the network switch. The paragraph in the FAQ I posted the link to above suggests 3 things to check on the Managed Switch.
