I have numerous Sonos products - playbars, subs, 1s, 5s - and several non-Sonos speakers connected through Sonos Connects. Have all been working fine for years. Lately, after starting system (TV or music) everything is fine for 10-15 mins, then the non-Sonos speakers develop a delay (stadium sounding echo). The Speakers are Bowers & Wilkens run through a Rotel RMB-1 Amp and a Sonos Connect on each speaker pair / channel.
