LG televisions made from 2018 onwards seem to be able to do it. I could test for you on a 2020 CX (WebOS 5.0) but I don't have wireless speakers to stream to. LG OLED sets can be excellent but their media player interface in WebOS 5.0 (the one I know) is absurdly lacking in convenience. Probably because the powers that be want everyone to join paid content providers, yes at least 5 of those, that do have nice interfaces (no surprise here).

Thanks for sharing this info jean-paul.
The way I read the LG info, is that is limited to streaming content from devices to the LG television. And not from the TV to AirPlay speakers.
Anyhow, are you able to into the menu of your LG TV?
Please check settings for Audio, and check if you can choose output to AirPlay speakers.

It is not my native language but it says the TV can stream content (specified as music) either to Apple TV devices or directly to Airplay enabled loudspeakers. For video content it says that can be streamed to Apple TV devices. My guess is that the sync function of the Apple TV device is a working solution for video content as audio only content can be enjoyed with delay without any penalty.
Can look for you but only sunday as I am away from home right now.

Thanks for checking @jean-paul and interesting !
What is the exact type / model number of your LG TV?

Yes, that's what I expected. So far I haven seen TV's that are able to stream audio from the TV to AirPlay speakers. A TV would need the same hardware as used for the 'Apple TV 4K' box.
The only TV's I have seen are Samsungs that can only do that with thier own Samsung WiFi speakers (proprietary protocol).
Or TV's (like yours) that support WISA.
So what I need to find are DIY modules with WISA support that can be used for integrating with speakers.
If you know such product or source, let me know.

There is little in common between WISA and Airplay. WISA is a standard for harware that streams audio over WiFi with extremely low latency on the order of a few microseconds and can synchronize multiple receivers (located in different active loudspeakers). Airplay's latency is more like 1 second and there is no tight synchrony between endpoints.

@KolfMAKER I have never seen WISA modules that are available for DIYers, only for corporate developers. Thats' too bad. I would love to use that platform!
@CharlieLaub Thanks!
You are right, WISA and AirPlay have little in common, but one important feature. AirPlay in speakers combined with AirPlay as used in the 'Apple TV 4K', is able to constrol and synchronize video and audio, resulting in no delay in the audio compared to the images on the screen. WISA does the same. So for the moment there are two challenges for what I want:

Those A31
The Linkplay A31 is about 8 years old--well before AirPlay2. The A98 was released about 4 years ago., and it looks like it supports AirPlay2. But the newer Wiim Mini and Wiim Pro look like they might be better options. I ordered a Mini yesterday and will open it up to see what's inside. I might even try it first 🙂. It doesn't look like the Mini uses an A98 module, because it is only a 2-core CPU, whereas the A98 uses a 4-core A53 CPU.
AirPlay2 can use WiFi Direct, which has the potential to significantly reduce buffering requirements. So, it might be fast enough to be useable with TV's that provide a small amount of lip sync correction.
An interesting feature of these new Linkplay products is that they have a built-in microphone to synchronize multi-room playback.

I can do synchronized audio playback with about 50-100usec synchroncity using Gstreamer and my home WiFi network with Qos turned on. That is plenty good for multi-room, and even almost good enough for separate left-right playback (but not quite). The problem is there is little in the way of video delay available from most TVs. The only way to do that is e.g. using VLC, that can delay video, but that is not helping you when your content is coming from e.g. a Roku TV.
