Lost surround and sub ( after update ?)

Also, we’ve got a thread going on at the Sonos Reddit here as well: 

https://www.reddit.com/r/sonos/comments/ubqrdr/ever_since_146/

I am also seeing this issue since the 14.6 update.

Arc + 2 Play 3s + Sub connected to tv and a Move that is in the group that looses sound after a few minutes.  It comes back if I remove the Move and add it back to the group but it always goes away again. Sometimes it will get sound for a few seconds but it is completely out of sync. The other speakers may be loosing sound but they are less noticeable since they are surround and the Move is off by itself.

My tv is a Samsung Q90R and my Sonos is not connected by ethernet.

Yesterday I removed my surrounds and subs from the system and re-added them. So far the issue hasn’t happened again. Will update again after some more time 

and it just happened again ahaha 

Sure sounds like a potential duplicate IP address issue to me. Or possibly simple variable wifi interference, particularly in the 5GHz range, although it could be from somewhere else. 

At the least, I’d unplug all Sonos devices from power, and reboot your router. Once the router comes back up, plug back in all Sonos devices, which will force them to both reload their own firmware, but request new IP addresses from your refreshed router. And then I’d be reading the linked FAQ. 

If it continues, submit a diagnostic to Sonos, who will be able to look at the hard data in the diagnostic, something that us denizens of this board don’t have access to. 

I appreciate the advice but I’ve already done all of that and I highly doubt it’s an interference issue as nothing has changed in this environment for almost 2 years. The fact that multiple people here and on Reddit are having the issue only after the 14.6 update leads me to believe there is some bug introduced with the last update 

Not sure if this is related, but last night I started experiencing a slight delay from by surround speakers (Play:1s bonded to an Arc). This was the first time I’ve ever encountered this issue since I’ve had this setup (since August 2020). I had to power cycle the Play:1s to fix it.

Nothing changed in my environment, either. Until I realized that the neighbor next door had installed a new wifi router that was interfering with all of the things I’d previously set up. Pervious to the neighbor issue, I had a microwave going bad that, when it ran, interrupted my kitchen’s ability to run any Sonos. Wifi and SonosNet don’t exist in a vacuum, unfortunately, and there are a lot of things completely out of your control that can affect them, and any radio signal. And those environments can change over time, not only by you adding things in your home, but those pesky outside influences. 

But you know your environment better than I do. Since I’ve only got a limited amount of data, I thought sharing the possibility might be helpful. It’s up to you if you’re interested in following it. 

Same issues but I just tried playing Spotify music directly to the Sonos after the issue started again and when in music mode, I get sound from the speakers!  

So, something is definitely wonky here.  

@Corry P sorry to call you out just wondering if Sonos is aware of this issue potentially introduced with 14.6
