Network Details (Including networking gear model/manufacturer and if on WiFi/Ethernet)
Eero system with wired backhaul. Roon core is is connected directly (wired) to a switch and then an Eero (and has been for years).
Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/etc.)
4 or 5 HomePods via AirPlay (wifi)
Devialet Phantoms via RAAT (ethernet)
Devialet Expert Pro via RAAT (ethernet)
Description Of Issue
Everything was working fine last night. This morning, however, Roon reports “No audio devices found.” The “Audio” tab in Roon settings is completely blank (tried on both an iPad and a MacBook). I tried restarting RoonServer and then rebooting the Mac Mini: neither made a difference. I also tried (based on a prior support thread for another user) stopping RoonServer and renaming the RAATServer folder to force Roon to create a new one. Again, didn’t make a difference; so I put the original RAATServer folder back.
So far as I’m aware, nothing changed between last night and this morning: no Roon update, no OS updates, nothing. Baffling.
The network is also working fine. I can play Apple Music via the HomePods with no issue and am, of course, using the network to send this report.
I restarted the Eero network (the app has a feature to reboot every access point at once), and that didn’t fix things. I also tried rebooting the server again. No fix.
I really have no idea what it could be. Everything was working fine yesterday. And now there’s nothing at all in the “Audio” settings, not even the outputs on the server (e.g., the Mac’s built-in audio output):
Thanks for the extra info, it’s a bummer the good ol’ reboot the network didn’t do the trick.
Does your Mac Mini have a wireless connection configured in addition to wireless? If so, can you try disabling Wifi on the Mac Mini?
Failing that, we’ve seen using Google DNS help with similar reports. Can you try using Google DNS and let us know if you notice a change? Here’s Eero’s instructions for how to change your DNS settings:
Tap the Settings tab, then select Advanced. Select DNS, then tap the Custom DNS bubble to enter your desired DNS server.
Ah! Sorry I missed that. One last try before I escalate this to the technical team to take a deeper look – let’s have you try a full regeneration of the RoonServer folder, then restore from a backup. If you have any backups from before you ran into this issue, use that backup in step 5.
