Control TV volume with Apple TV remote
Hello, until yesterday, I was able to control the volume of my old LG TV (2014) and my soundbar (noname brand) with the Apple TV remote (physical, not the application).
I was able to turn off and on my TV and my soundbar with the same remote too. The CEC option (LG Simplink) never was activated, and I never activated any option to control the sound of my TV. I just connect all my devices with HDMI cables and all worked perfectly.
But yesterday, during a movie, I turned the sound down but suddenly, the Apple TV remote stopped controlling the sound.
I didn’t change anything on my TV or Apple TV.
As it was sudden and unexpected, I think it's a cable problem. What do you think?
