Amp is on a table nothing near it. I have it hooked up to KEF q350 bookshelf’s and a klipsch sub. I have tried every combo of running with limited connections and finally with nothing hooked up or banana plugs in and after 20 min or so it starts cutting volume then cuts out and lights flash. I also tried plugging the amp into another outlet without anything hooked up and got the same result. 

Check out this article and see if any of the causes mentioned applies to your setup:

Have you referred to the  LED states FAQ?

Have you tried to call Sonos Support directly to discuss it?

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network. 


I am up to level 2 support and a lot of time invested that’s why I am posting on here. 


They’ll be much more capable, I suspect, than any of us here, since we don’t have access to the diagnostics from your system.  All we have to go from is what you’ve posted.
