My Sonos Arc Ultra is connected to my LG OLED G3 via eARC.
I also have an Apple TV connected to the TV, and I can control the soundbar's volume from it.
However, when I power off the Apple TV, the TV shuts down, but the soundbar does not.
Previously, when I had an AV amplifier connected via eARC to the TV, I could power on/off all devices using the Apple TV.
Is there a way to achieve the same with the soundbar setup?
Thank you in advance,
Kévin
