Sonos App controls no longer appear on your lock screen

I thinks it’s been clear all along that the Sonos app is merely a remote control, for the actual player that runs on the Sonos devices. The Sonos controller app has never been a music player, despite all appearances. It is a presentation layer on your device (computer, mobile device) for the actual system running on the Sonos players. 

Thing is, this is no different to the Spotify App when using Spotify Connect. There’s no music actually playing on your device in this scenario and yet the lock screen controls work. Clearly there’s a technical workaround to this problem, even if SONOS can’t figure it out/don’t want to use it for some reason.

What’s super frustrating about the situation is that SONOS’ “solution” is to unplug all your non-SONOS Airplay kit, rather than just provide a toggleable option to disable Airplay functionality on THEIR kit, which for most would be a workable compromise as lock screen controls generally add more value than Airplay.

suggesting that customers should be happy to remove functionality of unrelated equipment to accommodate their platform is simply arrogance.

The Sonos volume control just appeared on my iPhone X lock screen out of the blue. (Have 3 Sonos ones on S2).   It shortly thereafter went away.   How do I get it back?  Looks like it is fighting with Apple Music for control, but I have nothing playing via Apple Music on my phone. I see no way to change this in iOS.  My settings are correct on the Sonos app. 
 

In case I’m not the only idiot, I will provide advice - as I figured this out.  To have Sonos controls appear on iOS phone lock screen (I have an iPhone X) you must:

1. In settings/music on the iPhone turn off “Show Apple Music” (this does not effect using Apple Music via Sonos or the connection with Apple Music via Sonos). 
2. Open Sonos App (can use app switcher and be on home screen or use other apps though - just cannot completely shut down Sonos app)
3. viola -- Sonos volume controls (and what’s playing information) appear on lock screen.  By touching the top portion of the Sonos display on the lock screen, it takes you to Sonos App, so you can switch to another room/speaker to have the display now control the volume on that other speaker.

As far as I can tell - turning off “show apple music” simply stops it trying to connect via airplay to airplay devices (shrug) and overriding/forcing out Sonos on the lock screen.  And don’t play Apple Music locally, or it will override Sonos controls again.   Of course, if you have other active airplay devices, this might not work.

After being plagued with this issue for TWO years, here is the definitive fix:

1. Go to your Apple TV:
   • Settings > AirPlay & HomeKit > Turn AirPlay Off
2. Go to your Sonos app:
   • Settings > App Preferences > “Lock Screen Controls” toggled on
   • On the same screen, scroll down to the bottom and click “Reset App”
3. Close the Sonos app. 
4. Reopen the Sonos app and play music.
5. Lock your iPhone and VOILA! Lock screen controls are back! 

A few additional things to note:

• When you hit “Reset App,” a scary looking pop-up says that you are going to disconnect the app from your system. Don’t be afraid. Reconnecting it is literally just a matter of closing and re-opening the app. Super easy. 
• If you have an Apple Watch, that does not interfere with the whole “no other Airplay devices” thing. Seems to just be Apple TV.

Adam! I know I am reviving a 2 year old post, but THANK YOU! I was going nuts and it did it for me too! Now I have my control on Lock Screen , again. THANK YOU, Merry Christmas  be well stay safe!
