Play:1 speakers in surround system cannot control volume

I have a surround sound system of a PlayBar, Sub and two Play:1 speakers for TV and streaming. Since the last update I’ve had some issues.

When trying to mute the sound or change the volume via the buttons on the Play:1s, the green light comes on then goes out and nothing happens. If I restart the speakers, they will work for a short while and then fail again. They are performing normally otherwise and are visible in the app as part of the system.

I just remembered another issue. When I restart my Mac, the Sonos app can’t find the speakers until I go to System Settings > Privacy & Security > Local Network and flip the Sonos switch off and on. I know this is a known issue as I found the answer here when it first happened. I don’t know if that is an Apple or Sonos responsibility.

Finally, just to say that when logging in here, there was an error message I didn’t record (sorry) but a page refresh let me in.

Anyway, thanks for reading this. It’s just the first one that I need help on as the others are manageable for now.

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cannot generate the SonosNet which is generally the purpose to wire a speaker rather than using a Sonos Bridge (outdated and obsolete) or the Sonos Boost.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

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.

I see there is a designated “best answer”.

At this time, the speaker system is still misbehaving but on an intermittent basis. Without me doing anything, the Play”1s won’t mute or change volume using the buttons (sometimes a red flashing light) but then later, it is all good and working well. It has mostly been good and only short spells of not working. I have decided to put up with it and hope a firmware update turns up that will fix it whether it be from Sonos or on the router.

Anyway, case closed and thanks to the responders.

Since it is a 5Ghz connection to the soundbar, you could look into WiFi interference on the 5Ghz band.

The Sub uses the same private connection as the surrounds and should not be wired to Ethernet for the same reason. The Playbar can be wired, as long as you keep the WiFi radios set to On.

I see the same issue using an older playbar/sub/play1 surrounds setup. Mute on the rears used to work reliably. I can’t pin-point when it stopped working reliably, but as OP, I see mute working after restart, then after some time it won’t work anymore. My vol up and down buttons work, albeit delayed. But mute/unmute doesn’t work until a restart or if I pull the power on the play1’s.

Have you set DHCP reserved addresses, powered down all Sonos, rebooted the router and powered the Sonos back up?

Many "after a while" issues are address related and this will end them or expose a different issue.

Have you spoken to Sonos support to see if they can identify any issues with your system?
