I had four Sonos ones in a room with a sub woofer and everything worked flawlessly. Since getting the Beam and hooking it up with two of the Sonos ones and the sub for the full surround theater experience, and having the two other Sonos ones grouped separately, the sub cuts in and out intermittently and with no real pattern. I have tried unplugging and repluging, ungroup and regrouping, unconnecting and reconnecting, and re-running true tuning and it’s the same scenario over and over it still cuts out. Anyone else experiencing this? Any solutions?
