I’ve had my Beam for several months, and it had been working flawlessly….until 4/3/20. Now I cannot get it to stay connected to my tv. I’ve tried factory resets on both the Beam and the television, I’ve tried different cables, and I’ve even tried running the sound through the supplied digital audio dongle. I can get the Beam to connect to the tv, but as soon as I plug in the other HDMI cables (one for my FIreStick, and the other for my PS4 Pro), sound disappears, until I unplug the HDMI ARC cable from the back of the tv, and sound comes from the tv speaker. The Beam itself sounds fine and will play streamed music; it just no longer stays connected to the tv unless nothing else is plugged in. Also worth noting: initially, it was connected through my FireStick, because it controls our entire system, minus the PS4. But, now I cannot even get the Beam to connect to the FireStick. I’m unsure whether this is a Samsung tv issue, a Beam issue, or a FireStick issue.

Sounds like either the FireStick or the PS4 are identifying themselves to the TV as a speaker, via HDMI-CEC. Try looking through the settings for each device, and turn off HDMI-CEC on both of them, then test. This is not a Sonos issue. I’m unsure if it’s an incorrect implementation in the HDMI-CEC hub (the TV), or in the software of one of those two devices.
