I started to question on how the strict quality check was done on these Sonos Subs. I wonder if anyone out there knows. I have my Sub that I purchased back in December 2018, about 3 years old, that I found no longer working all of a sudden. This sub was used less than normal as we enjoyed our entertainment with few movies and TV shows. It was always placed at the same location by our TV. The cover is collecting dust but the sub itself is till without finger prints and shiny. Unfortunately the sub is no longer working and our 5.1 surround system is no longer. No light response despite the 20 second hold and change of power plug. Is there another trick I may not be aware to fix this or my 3 year old sub is simply out of luck?
