Sonos Beam not detected as Simplink-device (LG HDMI-CEC)

Question

I have a Beam hooked up to an LG Smart-tv (pre WebOS).

The tv supports HDMI-CEC (LG Simplink) and ARC.

Setup vas generelly very smooth and I had sound and remote-control via IR working  in minutes.

Unfortunately, I am not able to control the TV via Alexa. 

I went through the tv's various settings for Simplink, which included doing a full reset of the TV to set everything up from scratch.

Simplink is enabled and works perfectly for the attached Chromecast, which is immediatly detected by the tv as a Simplink-device, enabling control over the tv via the Chromecast.

The Beam is however not detected as a Simplink-device and consequently Alexa has no control over the tv.

The TV will turn on if I ask Alexa to turn on the Beam, but that is it. I noticed that other members have wrongfully concluded that HDMI-CEC must be working because their tv's were turning on as I describe. However, this is likely because of another function ( I think the name is HDMI auto-switch or similar) which enables tv's to automatically switch to HDMI-port when activated.

I have tried various suggestions throughout the forum, including disconnecting the Chromecast, swithcing cables, unplugging cables etc.

Do I need to do anything on the Sonos-side to enable the Beam to be deteced as a Simplink-device, e.g. enable the HDMI-CEC functions somewhere?

Hi Tejs, sorry for the delay, but I wanted to clarify a few things. Regarding this:Do I need to do anything on the Sonos-side to enable the Beam to be deteced as a Simplink-device, e.g. enable the HDMI-CEC functions somewhere?There's nothing you'll need to do setting wise with the Beam to get it to be detected. The HDMI-CEC is automatic with the right connections. Just make sure that everything's plugged in with a good cable and go through the TV settings. We have some steps outlined here for troubleshooting things. A great step for testing is to put the TV on the Beam's input and see if you can turn the TV off with voice.If you're stilling having trouble with HDMI-CEC, we'd be happy to look into this with you.

It doesn't connect to my Sony via Bravia Sync either.
