Description of Issue
Apart from the occasional minor glitch adding albums from Tidal / Qobuz to my library Roon has been working working well. Today I connected the Synology NAS and Linns to a different network and it couldn’t find Roon. I restored from a backup which changed the problem to it asking “Are you online?”
The NAS has 2 ethernet connections so I just swapped to the other (which is the one which was connected to the old network) but now Roon says “Searching for Roon OS Core”.
I’ve restarted everything a few times. The network is online. I can access the Roon Core folders using Finder on my Mac. However the Roon software on my MacBook, iPad and iPhone cannot find the Roon Core.
Do I need to “Select a different core”?
If I do, will this lose my settings and history?
Yep, I’ve restarted everything. The app is stuck “Looking for your Roon Core”.
(Smoke me a kipper, I'll be back for breakfast!)
Not a network expert but this sounds like a classic case of your Roon Remote and Roon Core being on separate subnets of your network.
Can you access your router or use a program like Fing. To check the IP addresses of gear on your network?
Your remote and core need to have the first three sets of numbers in the IP address the same.
I gave up and connected my audio system back up to the old network. That didn’t work but the Synology has 2 ethernet connections so is connected to both. When I jumped onto my main network (the one I was trying to move over to) the Roon Core was suddenly visible. Had to restart everything a few times but eventually Roon could find the Linn streamers too.
Haven’t got a clue what the problem was but i can listen to music again.
Unfortunately I still can’t listen to BBC radio stations. That was the reason I was moving from my (US located) VPN network to my regular UK network. The Linn app can play BBC Radio 4 but Roon gives this message:
“Playback was interrupted because a track failed to load”
I read this too some time ago on the Naim forum when there was much complaining when this happened, but not sure if it depends on station and geolocation? I am in Germany and have these BBC stations (but no others) in Roon and they all play:
Thanks for getting in touch, @Suedkiez. Could you tell me the URL you are using for Radio 4 please? That’s all I really need. Radio 3 and 4 Extra might be nice but it’s Radio 4 that I listen to regularly.
Yep, that’s what I’m getting but since I’m in the UK I’m also being offered the 320 stream but neither works.
Another user had the same issue but his core is a QNAP NAS and the issue was a FFMPEG that disappeared when Roon was updated. No idea what a FFMPEG is and doubt Synology and QNAP will use the same one so might be best to start a new thread.
Synology’s OS does not have a full suite of FFmpeg CODECs (I have no idea what half of those words mean) so one has to be manually added which is very simple once you’ve worked out what to add and where. You can download the FFmpeg from this chap’s website:
