Has anyone had the issue with a Play5 Gen 2 randomly dropping off system with orange and white flashing LED. That reappears with a power cycle? 
 

I bought 2 play 5 gen 2 a few years back to use as a stereo pair. 1 of them recently has started to drop out and display a flashing orange and white LED. If I power cycle it fixes the problem for a day or two. They are built into our cabinets and are a pain in the neck to get at to power cycle. I’ve now run Ethernet cables to both but the issue remains. Sonos support says my amplifier has a fault and have said they can give me 30%off a new one but I would need to buy 2 as the new 5 won’t pair with the old! Just seems strange that a power cycle can resolve a hardware issue? Anyone had a similar issue? Or have any other ideas on a fix?
