I find it strange that I wake up one morning and find my sonos system down, the S1 app suddenly can find any of my speakers all gen1.

After many failed attempts of resetting etc sometimes the app would see the speakers other times not. On the times it did it always failed to connect. 

Now use the new app hey bingo everything is there, I could up date the play ones to use the new app. My Play 5s however whilst can be seen, they are not compatible.

I kind of remember they tried to brick these before, looks like they may have done it now. 

Well sonos as the rest of sonos products give up. I promise you the replacements will not be Sonos.
