iPhone Volume Control

​Hi @hoganhaley,

Thank you for reaching out to the Sonos community and for letting us know about your concern. Let me share some information about how you can control the volume of your Sonos system.

You can control the volume on the Sonos app on your iOS devices, on the Sonos speakers, using voice commands like Google Assistant and Alexa on a voice-enabled speaker like your Sonos Move. On iOS devices, you can control the volume if Hardware Volume Control of and you can control your Sonos system on the lock screen.

Lock screen controls will not appear in the following scenarios:

• A non-Sonos AirPlay capable device is present.
• Disable the AirPlay feature on all non-Sonos AirPlay endpoints to allow lock screen controls to appear when using Sonos.
• Another app on the device is playing music or video.
• While connected to a Bluetooth audio device.
• VoiceOver is enabled.
• Headphones are connected to the iOS device.

iOS devices don't provide a way to control devices on your home network from the lock screen, the controls are only available for audio being played on the device itself. The Sonos implementation of lock screen controls was built in a way that's no longer viable and with the launch of AirPlay 2 on Sonos, we made the decision to remove the functionality in households that use AirPlay.

Hope this helps. Please let me know if you have any further questions or concerns, we’ll be glad to assist you. 

What does this mean? 

“On iOS devices, you can control the volume if Hardware Volume Control of and you can control your Sonos system on the lock screen”.

Again, I cannot control volume unless I have the app actually open and active.

I can do nothing from a lock screen

Did you follw the advice given in the second link (Control Sonos from the iOS lock screen | Sonos).

To the question above, yes. Again, nothing shows on lock screen.

But I just inadvertently discovered something.. Unbeknownst to me I can airplay the Sonos system through to the speakers from the Iphone music app, Tunein App...etc. And I can then control the volume from the lock screen.And I can control the individual speakers as well.  But  strangely enough, if I use the Sonos App for playing music, radio...etc, I cannot control the volume unless the app is open on my screen.  And yes, I do follow the advice as given.I have uninstalled & reinstalled the app & no change.

So do I have this correct that you can only control the volume from lock screen if you are using airplay?

Just solved the mystery. I have Apple TV. If I am playing music or whatever through the Sonos App with  Apple TV hardware been plugged in, cannot control volume on lock screen. Unplug Apple TV, magically can control on lock screen.

That should be front & center on Sonos Lock screen help page.

But that is also what the link refered to by @Rowena B. and @106rallye says.

 By saying “ A non-Sonos AirPlay capable device is present”? 
if that’s the case I certainly didn’t realize my Apple TV  device was that. Guess I should have  and in retrospect makes sense. Still say that should say ie Apple TV.
