I have a Sonos One in the kitchen, which until a feew weeks ago worked flawlessly with roon. Now, irregularly , roon loses connection to the Sonos box. The device doesn’t show up any more under audio zones, and it isn’t shown in settings → audio.
Only the sonos streaming protocol is affected. The sonos can be seen as an airplay device (and works via airplay). A restart of the Sonos doesn’t fix the problem, I have to restart roon server for the device to show up.
It seems to happen out of the blue, I can’t tie it to any actions of my part. I just open roon, and the Sonos audio zone has vanished.
It sits like a meter away from the router, with just a wall in between. What’s more, it worked flawlessly for some time now, and still does if roon doesn’t loose the sonos streaming connection.
I can still play to the speaker via airplay or the sonos app if the sonos streaming connection in roon is lost. So, no, it’s definitely not the connection.
This is something that’s been affecting a number of Sonos users for some time. I myself never had an issue with my Sonos Arc been rock steady on wireless since I got it in September, it’s on latest Sonos firmware etc. So likely some environmental thing combined with some changes in Roon that’s causing it. Airplay is discovered over mDNS, Sonos streaming doesn’t so this explains why you see it via one and not the other, something is stopping Roon seeing the discovery broadcasts needed.
It’s now a long term problem that Roon are investigating and said they working on.
It affects a fair number of us, and it’s not our network’s, it’s something in discovery that is broken as they just disappear and will not come back until a restart of Roon.
If your Sonos One has Airplay I would use that.
I have started pairing my order Sonos devices without Airplay with a Roam or Move and using Airplay to play while grouped in the Sonos app.
It means they can be on all day without dropping off. It’s a workaround and not a fix, but @noris is collecting log files etc while trying to narrow it down.
I just started having this issue after a recent roon release… I have a pair of Sonos SLs, Arc/Sub , roam, and a move… all disappear from roon… I can reboot the roon and they will reappear but then disappear. Rebooting router does not help either.
We have a ticket currently active regarding this issue and our team is looking into this. I can’t comment on timelines, but we are aware and investigating a path forward. If we need any additional information for our investigation we will let you know. Thank you!
You and me both Ira, I am currently using a Roam and a Move to anchor my older Sonos devices via Airplay as they do not support Airplay streaming.
The good news is that it has been 100% reliable doing that, even if not ideal
FWIW I was having a look in my router settings about 3 weeks ago.
I had IPv6 enabled still after messing around with something during May.
I disabled the IPv6.
Since disabling IPv6, my sonos devices (1 x play 5 and 2 x play 1 - all on wifi) have been stable.
This was prior to latest roon release. Post latest release, the zones are still stable.
This is now 3 weeks of stability.
Might not have anything to do with IPv6 but thought Id post for info as its the only thing I changed in my network.
For info, I also have both IGMP snooping and IGMP Proxy enabled (these have always been enabled) on my router settings
My router is a Synology RT2600ac.
Ogdens I have done the same as you and never had IP v6 enabled. I did have about 6 months of total stability between several releases until it broke again, after another update.
I have tried running just one device and only on WiFi, but nothing makes it work for more than a maximum of 12 hours with an average of about 4-6 hours.
I am more committed to Roon than Sonos, and planning on replacing a couple more rooms as well.
Going to limit myself to garden, kitchen and conservatory in the future, and use them linked via AirPlay (using Move and Roam). That all works perfectly but SonosNet is a disaster for me now.
Pretty much given up on this being fixed
