Sonos finally put playback controls back on the iPhone Lock Screen using Live Activities, and if your household runs on Sonos speakers, this is the update you should get from the App Store this morning. My wife and I are long-time Sonos users (we have some S1s). I literally just updated my app and my wife’s.
The setting isn’t obvious to find, though. It’s buried in the app settings, so head over to Account > App Preferences > Live Activities. Once you activate it, you will see it on both the Dynamic Island (assuming you have space for it and there aren’t other items running) and your lock screen.
What is truly nice about this is that you can view what is playing, skip songs, pause playback, and adjust the volume of your speaker(s). And clicking on the Live Activity will launch the Sonos app. Also, once you leave your network (and I haven’t tested this yet), I believe the Live Activity will disappear, since Sonos requires you to be on your speaker network to use it.
