Volume Slider missing

Without commenting on the suggestion to “start a class action suit” as that horse has been beat to death. Try calling Sonos Tech support. Also as one speaker is the Play 5 Gen 1 you need to be using the S1 controller. At least for the Play 5 gen1. The others speakers will have be downgraded to play under the same S1 controller. If not you’ll have run two separate systems. 

I selected Play 5; Gen 1 because I know it’s old… but not sure it’s actually Gen 1.  It does work fine.  All 3 speakers worked fine for over 2 years, until this network change.

Please tell us what device (iOS/Android) you are using with the Sonos app.

Android on Samsung Galaxy

Update:  reset factory AGAIN on the Sonos One SL that had no volume slider.  Named the speaker differently.  All 3 speakers had volume controls and functioned properly.

Next day, the 2nd Sonos One SL now had no volume slider.  WTF.  That is the one speaker in the setup that hasn’t had an issue.

Today, the 2nd Sonos One SL has the volume slider back, but the other 2 speakers have no slider.  I did nothing… no power cycle, no disconnect, no resets, nothing.

It seems like the app just randomy chooses which speakers should not work each day.

Also, the app will not connect to any music sources now.  How does SONOS not address this garbage?

Signs of IP conflicts. These often show up after a router change because the new router, having no idea of the current IP assignments, issues a new IP that is in use by another device.  To cure this, do the following:

Reboot/power cycle your devices in the following order:

Modem
Router
Switches or hubs
Wired Sonos units
Wireless Sonos units
Computers/printers
Wireless devices - phones/tablets etc.

Allow each device to come back up before proceeding to the next.  Note that you can permanently prevent duplicate IP addresses by assigning an IP to each device's MAC address in the router setup.  See your router manual for details.

After replacing the router one must reboot everything (following the above order) on the network — else there might be intermittent mayhem. SONOS is very active on the local network and more likely to be impacted by unfortunate IP address conflicts.

Refrain from any SONOS Factory Reset without further consult. 

Gave all 3 speakers a static IP.  Reboot entire network as stated above.  2 speakers have volume control.  1 speaker still does not.  Cleared data and cache on app… no change.
I’ve now wasted 3 whole days on this.  Still convinced that the issue is with the app.
Anything else I should try to get the 3rd speaker to respond??

Same problem here 

existing 3 year Virgin network. No changes 

I have 4 Sonos speaker Sonos play 1 / play 3 / symonfisk bookshelf / and then the fickle “One SL”

All speakers have volume controls except .  The SL !

this keeps intermittently happening.
I’ve manually updated the SL tonight.  although I had auto update on.  It had ignored this offer.. so I had the Sonos app,check for updates and it said oh yes   There’s  SL needing update 

so it streams music fine but refuses to let the app on both my iPad or iPhone control the volume 

everything reset   No change.   Volume controls on top of speaker work fine. 
 

if it was an ip conflict then surely it wouldn’t stream music !    There’s no issues with anything else on my network and no conflicts reports  
 

the old app was much more reliable. 
frustrated 😣 

Is the SL up to date? Temporarily wire the SL to the network and check for updates.

You also can view the various software version at Settings → General Settings → About Your System

As above. All apps and speakers up to date    Everything reset several times 

As above fella said.  I gave up in the end …  

BUT

2 hours later the volume control on the SL appeared on its own 🤷🏼‍♂️

music streams perfectly but I think it’s a communication problem between the App on iPad and OR iPhone …. Particularly with the SL (although this bit might be coincidental)

intermittent glitchy comms

My opinion is that a software  app to speaker software reset somehow needed when Comms established.   Never saw this issue in the old app 

works ok  today (2 days later) .  So until the next time 

PS I’m an IT guy and understand IP stuff. &  I’ve installed loads of Sonos systems for my customers and still love them 😊.  Just off to Spain to install some Fingers crossed 🤞
