Hi there,
My Sonos Beam is lowering the volume automatically just after I turned it up. It lowers the volume to the same value (15) again and again. It does not matter if I control the volume on the beam itself or via different apps (sonos app, spotify android or macOS, tv remote). I already tried unplugging the device, wait and rebot but to no avail. The light on top of the beam is also blinking white and red. I have not touched or moved the beam or cables in ages.

Hope you guys can help me out here.
