Hello,
I’ve spent three hours today calling between LG and Sonos Customer Support and know one can really help. I tried everything from turning off the TV/Soundbar for 30sec. Adding a new device in LG even using Philips instead of Sonos. Deactivating eARC in the LG setting, and I'm super frustrated as you would think a 1700 USD dollar TV and 400 USD soundbar would sync properly, and instead I get no tone over the Soundbar and the TV remote setup for Sonos does not work.. Does anyone have the same issue or is it just me???
