What model TV do you own? Have you turned on CEC in your TV’s settings? Have you performed the TV Setup process in the Sonos app?

LG 86UK 6500. .. as far as i know i have done the whole setup in the app. have had sonos playbar for years.. ,, CEC i don´t see that in tv,, been trough i think all tv audio possibilities..   The strage thing is it works after few annoying plug and unplug tv/ arc attempt … but just for a while, then silence.

i see now , yes the CEC is on.

Do you have any other external media devices connected to the TV?

Try this:

Disconnect everything including the Arc from the TV and unplug the Arc and TV from power for a couple of minutes. Plug the Arc and TV back in but keep everything disconnected. Make sure Simplink (CEC) is turned on in the TV settings. Run the TV Setup process under the Arc’s settings in the Sonos app and connect the Arc to the TV’s HDMI ARC (HDMI 2) port when the app instructs you to. After the Arc has been successfully connected to the TV, connect your other devices to the TV.
