You may want to start with a factory reset of the device to remove all details of previous ownership...
Unplug the power cord from the electrical wall outlet.
Press and hold the Play/Pause button while simultaneously plugging the power cord back into the electrical wall outlet.
Continue holding the Play/Pause button until the light begins flashing amber and white.
Once reset, the light will flash green indicating the product has been reset and can be added back to your Sonos household.
This way you can connect to a new, clean system.
