I have just bought LG 65C14K oled 2021 and I can't seem to get it to recognize Yamaha RX-A840 which use for surround sound, used to work with my old LG 55LA 6230.
Is the Yamaha RX-A840 not compatible with LG 65C14K something to do with Dolby Atmos.

as long as you connect the eARC output of the TV to the HDMI Out on your Yamaha. HDMI Control needs to be turned on via the Yamahas setup menu. You also have to setup the same on the TV(HDMI Simplelink CEC)to output audio to your receiver.

Sony 77" A80J OLED, Panasonic UB820, Panasonic BD-T460, Apple TV 4K 3rd Gen, Samsung Q990D Soundbar

HDMI control caught me out to. Once turned on both ends it worked fine.

If that doesn’t work can also try turning TV on first, then turn AMP on. I have one set up with older gear, where if do it the other way round get no sound.

Once everything is working, turning TV off and on should auto turn AMP on and off. The off works with my older equipment but not the on, so I just have to remember to do in correct order.

I haven't read into this thoroughly, but do recall someone else having audio issues with the same tv and a Yamaha receiver. Here's the thread on that, in case it's of any relevance:

I have got it working but is only showing sound in PCM as on my previous TV set up it would show Dolby Digital.

I don't know if its possible or is something to do with Dolby Atmos?

You don't want the tv outputting PCM as that's not going to give you DD, Atmos etc.

As luck would have it, this was raised in another recent thread in relation to an LG TV!

Dolby Atmos should be turned off on the TV as your amp doesn't support it. Digital Sound Output should be set to auto, and eARC to off.

I have finally got it to work with a Sony DVD player it works showing Dolby digital with the connected speakers, still can't figure how to Dolby digital with something from Apple TV content from the Oled Television seems like can't quite get the source right.
