Sonos surround no longer works with new Xfinity box and voice remote
We switched to a new X1 box and our Sonos surround speakers no longer work. The Voice remote controls the sound bar, which is hardwired to the TV but the surround speakers do not work with the TV. If the old box is reconnected, the surround speakers work. If we switch to a music app such as Spotfiy, the surround speakers work ( in both cases the sound bar works, too). Seems like this is just a setting somewhere but we can't find it. We've also reset all Sonos devices, the speakers, the boost, etc. The wi-fi is not having a problem.
