So, I have a client that wants to replace a TV. He wants a new LG Oled, with the Magic Remote. From what I can tell it should work, even though it is partially rf control.
Has anyone used LG, with the magic remote connected to a Playbar successfully??

Yes.

Volume should be rf, but there’s some settings you can go through when controlling soundbars and pick one that then turns it to ir then you can learn the commands in.

I did find an option like you say here, but it was a few years old. Ironically, it said to choose Phillips TV code to learn into the the Sonos Playbar.
Have you actually done this recently with an LG?

Yup. I just did this recently with a newer LG Oled and a Playbar. Sonos was listed as an option

That is a bit of a red flag, since a PlayBar has no built-in codes at all. It only works on IR when you learn in a code from a TV or other infrared device.

Maybe LG has it in there soundbar menu to make it easy for a homeowner to add a Sonos device?
We know that Sonos just learns what it given to work.

I’ve started seeing “Sonos” listed as a manufacturer in TV’s. I haven’t been keeping track of models and brands. I saw this in a new LG yesterday. Maybe Sonos has included a default set of IR codes that a manufacturers’ database has picked up.

Xfinity has had Sonos listed as an audio device for years. I've programmed countless Xfinity remotes to control Sonos playbars. LG has Sonos listed as a controllable audio device. The magic remote controls the playbar with Sonos commands. The playbar does not need to be programmed to accept the command. Sonos codes do exist and they are readily available.

I can only say for sure about the Playbar, but there are IR codes built in that work without anything being learned into it.

Good to know, thanks, all!

RC at its best!

I can say it for sure on the Beam (at least the ones that are/were S1/S2 compatible)
