I have multiple sonos devices. All of them are placed on WM = 0 as my ARC is wired.
All other devices (Sonos Play: 1, Sub, Sonos Ones, Sonos Play_5s) are all on WM = 0 apart from a single Sonos One. I have power cycled it, factory reset to no avail.
If I factory reset and wire it, it will show up as WM = 0; however as soon as I unplug the ethernet cable out of the One it goes back to WM = 1.
you help is appreciatted!
