I just installed the newest update and suddenly my play 5 has no sound. It shows to be playing on the controller and shows connected. When I plug the headphones into the headphone jack on the back I get sound and the volume controls on the unit function properly, however without the headphones no sound is coming out of the speaker. I contacted Sonos support and was told that the amp in the speaker has gone out and that the timing of the update was purely coincidental. I was using the speaker as well as several other Play One units moments before installing the update. Has anyone else had this issue or know how to solve it? I was told that I will now need to replace the speaker that was functioning perfectly fine literally seconds before installing the update.
