My setup is a new LG OLED C1 from 2021 connected over eARC with a Sonos Beam Gen. 2.
How this setup does:
When adjusting volume with TV remote, I get a visual indicator in the tv screen, that I press + or - on the volume buttons. No numbers, that show on what level I am actually on the Sonos Beam Gen. 2.
What I do have in addition is an Apple TV 4K.
How this setup does:
When adjusting volume with Apple TV remote, it works as well through CEC, but with the difference, that then I don‘t see it visual on the television, but the Sonos Beam Gen. 2 status led flashes during pressing the volume buttons.
Why is the behaving like that?
