Hi

I have Sonos Amp (about 3 years old), connected to TV and two B&W Speakers with Wharfdale passive sub. Brilliant.

I had a Samsung Smart TV, and ARC worked well.

I now have new LG CX 65” TV, and have issues with ARC.

No ARC Audio passes to the Sonos. I have to use “Internal Speaker” on the TV.

Sonos is now off/standby, useless, and gathering dust…   :-(

It once worked after a power outage, some sequence of power-on may have coincidentally worked.

This was only once, till I switched the TV off. After that, I had to go back to “Internal Speaker” on the TV again.

I have tried many times, all combinations of settings.

Sonos 2 App on iPhone fails to connect to TV.

I did a Diagnostics = Ref 2071482316

Please could you assist?

Thanks

Do you have Simplink enabled on your TV? Have you tried unplugging the Amp and TV from power for a couple of minutes? You can also try using a different HDMI cable.
