Sonos System settings seem to Drift and require power cycling to restore

I have a sonos arc soundbar and era 300s with a sub mini in my living room. along with a Sony Bravia A80J Google TV They seem to keep changing their configurations such that they require power cycling of either the speakers and or the television in order to restore their configuration. Is there a way to restart them remotely or to do something to reset rather than having to walk to them each and unplugging and replugging them?
