LG 55UH850V not outputting to Beam

The TV is recognising the device and Sonos support confirm that the Beam is sending packets to the TV, but nothing is coming back. LG support are sending out a tech to assess. The HDMI ARC port (#2) works as an input fine. This is the first time I have connected an ARC device to it (i.e. I am asking the TV HDMI port to output). I've played with all the limited settings I can access (PCM/Auto) and SIMPLINK) to no avail. I'm happily using the optical adapter for now though am keen to get this sorted to gain the additional functionality. Could just be a fault on my TV (or a service setting change required). Has anyone had a similar experience? Very impressed with sound quality on the Beam and it can handle something that I found the Playbar could not - playing music in full mode from the Sonos Connect in uncompressed mode I am not getting any drop outs - 🙂

    Hi everyone, if you're still having trouble, this thread may help solve the issues you have setting up or using the Beam with certain CEC commands. It might not help with all issues, but it's a good starting point with the basics covered, so make sure you read through. If you're still having trouble after that point, I'd suggest give us a call on our support line.

      Same problem. Sonos Beam worked when plugged into LG TV but as soon as I plugged my Spectrum / Time Warner DVR into another HDMI port, the Beam stopped working. Turned off TV and unplugged DVR and turned TV on. Worked fine again until I plugged the DVR back in. After several hours on the phone with very helpful Sinos rep, he suggested an old HDMI cable without CEC which stands for Consumer Electronics Control. After researching online further, I learned CEC runs through pin 13 on the HDMI cable and so rather than buying an old HDMI cable, I found on Amazon a Lindy CEC less HDMI adapter. It was about $20 but worked perfectly. I just attached the small adapter to the HDMI cable connected to the DVR and it stops the interfering signal from the DVR (which isn’t supposed to have CEC, but apparently sends some type of interfering signal through the cable). This does not really seem to be a Sonos problem but they were very helpful and knowledgeable unlike the Spectrum people.

      I should have been more specific. When unplugging the DVR, I mean unplugging the HDMI cable from the DVR to the TV, not the power.

      Worked via HDMI only when I removed my Virgin Tivo box (connected via Neet splitter). Stopped working when I reconnected. Have just order Lindy HDMI CEC Less adaptor (£9 on Amazon). Judging by the item reviews and comments above that should resolve the issue
