Play:1 speakers in surround system cannot control volume

Just guessing here.  I believe if the ONEs are “bonded” to the PlayBar as surrounds the volume controls on the ONEs would not be expected to work.

Hi. The volume level and mute worked on the whole system until recently from either of the rear surrounds buttons. As I said, functionality comes back if I power them off/on but that is getting stale.

Hi

Regarding your main issue please note that new updates for the App and hardware were recently released. If you’ve already installed them then try this

1. Unplug your Sonos
2. Reboot your router and let it come back
3. Plug in your Sonos and let them come back
4. Open the Sonos App and select Join an Existing System (best done using your phone or tablet)
5. Test your Sonos

Your 2nd issue is Mac and Sonos related.

1. Make sure that UPnP is enabled in the Sonos app
2. Have you updated the MacOS?

Your 3rd issue is something that happens on occasion. I get it also more times than I’d like. Very frustrating. I’ve mentioned it to the Moderators as IMO it’s a GainSight issue. Full disclosure it started happening on my devices about a year ago. I’ve gotten the error on iOS, MacOS and WinOS.

Hi. Everything has been restarted recently (within the last week - the Sonos and Mesh router system and other stuff) so I’m not thinking of doing it again.

I assume you mean the Mac app for issue 2. I can’t see a mention of UPnP anywhere in Sonos > Settings. I can live with that being a hiccup for now as it is only after a Mac restart and I’m hopeful it will be fixed sometime soon.

That’s your choice regarding the restart of Sonos. However, it has to be done in the order outlined. You also have the option to run a diagnostic within 10 minutes of the next occurrence, make note of the reference ID and call Sonos tech support.

Thanks on the UPnP. iOS app :D  The two settings mentioned in that link were both ON. That’s not an obvious place to go hunting, at least not to my mind.

I’ll hold out and hope the next Sonos and/or macOS updates help. It worked for many, many years and only ‘broke’ recently. I thought I’d ask to see if it wasn’t just me. Seems it may be.

As long as the network refresh was done after the update was applied it shouldn't be a problem. If it was done before the update it may need to be redone.

If  the refresh is needed too often to be convenient reserving DHCP addresses for all Sonos usually eliminates the issue. 

It was done after. I had issues with a ‘smart’ device so did the mesh power thing for that. Sonos has also been done a few times just to see if that helped but now it hasn’t, I thought I’d look in here. It’s weird how it can be cured by restarting the Play:1s but only for a short while. Regarding them, one is on Ethernet and the other is wireless because I can’t wire that one. I mention that because they are both misbehaving, it isn’t likely to be that. Or so I think.

Surrounds speakers should not be wired via Ethernet. They receive needed information from the proprietary 5Ghz frequency transmitted by the Playbar.

Also, speakers setup as surrounds cannot generate the SonosNet which is generally the purpose to wire a speaker rather than using a Sonos Bridge (outdated and obsolete) or the Sonos Boost.

I suggest you remove the Ethernet from the Play 1. Then in the app remove both as surrounds from the Playbar and set them up as surrounds again. 

Yeah, wiring surrounds is not recommended.  Though it may not be intuitive, an Ethernet connection is actually slower than the one way, direct 5 GHz connection between the soundbar and sub/surrounds.  Ethernet still has to hop back to the router whereas the direct connection does not, and that can cause all sorts of connection problems.   

Just to finish this one up, I did pop the Ethernet out and restart the Sonos. It is now back to as it should be and hopefully it will stay on track (no pun intended). Re-starting did fix short term before but hopefully the wired connection was the culprit. Maybe I’ll de-Ethernet the Sub and PlayBar at some point.

If you continue to see issues at restart, update or power restoration it can often be prevented with DHCP reserved addresses for all Sonos. Once set power them all down, reboot the router and let it stabilize, then power the Sonos back up.
