No Controls on iOS lock screen

Maybe see/check the limitations/details mentioned in these Sonos Support documents:

Hi everyone 

I have the same issue. I have tried all options mentioned above and tested it  my iPhone7, iPX, iP14 and iPad. No BT, no ATV, control enabled on app…  There is no controller shown… iPadOS16.4.1, iOS 15.7.3 and iOS16.41. And it worked few weeks ago for me as well.. 

Very frustrating...

Any Airplay beacons on your network, Apple TV perhaps?

I was changing the wifi network I use with my amplifier today (Lyngdorf TDAI 1120) and following the setup process to add the device as an airplay speaker.

I ended up getting artwork on the lockscreen when playing through the Sonos Port (not via airplay).
 

It looked like this: 

I loved it. No idea how I did it, can’t get it back, despite trying for an hour, disabling all other airplay devices, etc. Ridiculous really.

It’s been gone since my last post above, but is inexplicably back now. 
 

Is it only a minority of users suffering from this? I wonder what we all have in common. I’d love a solution!  
 

Do you not think it’s perhaps one, or more, of the lock-screen ‘limitations’ mentioned in the Sonos support articles linked in my earlier post above?

I don’t think so. 
 

I’ve read through them and none are applicable in this case, but I do appreciate you you taking the time to check.

The only grey area is my Lyngdorf amplifier which has an Airplay function. I have tried to disable the Airplay input, but it still shows up as an option from the Apple Music app. However, it’s currently showing up and my lockscreen art and controls are functioning, so I’m assuming that’s not the issue.
Are you an iOS user for whom the lockscreen controls work perfectly 100% of the time?

I am an iOS user, but I don’t use the Sonos lock-screen controls, because I have Apple TV’s upstairs and downstairs, so the controls (obviously) would not work for my setup here, because of those operating on the subnet. In the distant past, whenever I’ve just ‘tested’ the feature by switching those ATV’s off, enabled the lock-screen controls in the Sonos App and rebooted the network, the controls  have appeared on my iPad/iPhone and worked okay, but I prefer to have the Apple TV’s, rather than the Sonos lock-screen controls. So can’t really assist to answer your question.

@only_sleeping,

You may want to also research the bonjour ‘discovery’ service too - perhaps start with this link:

https://support.apple.com/en-gb/guide/deployment/depf138dd79c/web

Some devices/routers can ‘apparantly’ have intermittent discovery issues and I suspect that may introduce some ‘intermittent’ issues with iOS lock-screen controls too… but it’s not something I’ve personally researched in any depth, as I rarely use the controls, as stated, but maybe it’s related to why you have some intermittent issues with the controls.

I would definitely reboot the network if you change settings and maybe switch off features like ‘WiFi Calling’ and ‘Private Address’ (MAC address spoofing in the properties of the network connection) on your mobile iOS devices, just to see if those things may assist too. 

Interesting. Last time the lock screen worked just after setting up a new router (my broadband had been upgraded).

This afternoon, my router has had...some kind of episode (and some of the devices ip addresses have been reset - maybe an error and then a restart?) - now the lockscreen controls are back. I’m unsure what’s happening here, but maybe something on the network is changing and blocking the lockscreen.
