Lesless sound, trolololol, this is new.

Seems a waste the TV supporting lossless sound. Audiophiles have 10.2 systems bi-amped and would never use TV speakers.

I think it extends a little beyond the TV speakers - e.g. being their smart tv function supporting say video playback with Dolby True HD / Atmos. E.g. if their TV can process signals with lossless HD audio over multiple channels, they can do a signal pass-through over HDMI-ARC and thus feed receiver / soundbars HD audio / HQ / multi-channel True HD and Atmos signals. I know I'd like that 🙂

I did not understand the article
If I have a LG B7 from 2017
How do I transfer the sound to the AVR?
After all, the TV has only SPDIF output
Where does lossless and uncompressed audio format come from?
What happens if I connect from my HDMI computer directly to the AVR?
And HDMI to the screen?
Will Atmos within the TrueHD sound less good?

HDMI-ARC. Although that seems quite a big task for its also of carrying the video signal.

SPDIF isn't compatible with newer HD surround technology. You should use HDMI if it's supported on your AV amp.

Its a pity they do not sort out the terrible lip synce issues that happen on both the 2016 and 2017 range of LG OLEDs when using the TV's internal apps (iplayer, youtube, netflix etc). Its no good adding stunning audio if you can't correctly sync it to video LG!!!

One: I do not have this issue, and i have a OLED65B7A
Two: Even if this is an issue on some, LG has a very nice and easy to tweak sound delay option to fix it.

Why would you EVER use a Television's speakers over a decent home theatre setup? If you can afford one of these brand spanking new OLEDs, I suspect you can afford a decent receiver and speakers. I don't care how good the sound is on these things, it's not going to hold a candle to good speakers.

Because some people care more about the visual aspect of their home installations than any percieved sound quality advantages?

^ Decent sound on a TV, because as you can see, it essentially has a sound bar attached. That's what that bottom portion. The negatives to this is, many people find that to be a dated look, and there is no subwoofer.

^ Not even remotely good sound quality, and there is absolutely, 100% not "perception" here. You can not get even decent sound quality from a TV that has to shove any and all the sound either towards the floor, or the back wall. It's impossible. It's not a "perception". You might as well make a homemade, cardboard box speaker, as you'd get better soundquality from that.
Now, i'm not saying that someone can't be satisfied, enough, with the TV speakers. But i agree with who you replied to. Considering this is an OLED thread, the fact that you'd spend thousands of dollars on a TV, and can't be bothered to spend even $70 on a soundbar to better complete your entertainment, is just...strange.
...percieved?
Like, i understand when people say they don't need a soundcard.
But, perceived sound quality advantages?......from built in TV speakers, to a soundbar/sound system?
.....
What?....perceived?
These are facts. Though some of LGs built in speakers are actually nice, considering instead of just slapping speakers on it, they essentially attach a soundbar onto it, there is nothing "perceived" about the sound quality differences between a soundsystem/soundbar vs a TV, TVs with soundbars attached aside.

I have gone to shops myself and confirmed the issues happens on both the B7,C7 and E7 and it is impossible to fix with LG's sound delay option (because the option does not work correctly and does not allow the picture to be delayed enough. I personally have had three differen E6's and all have had this same issue and has been in Lg's hands waiting 7 months for them to fix.
You must be one of the lucky people not experiancing the problem or have a build of the OLED (panel revision) that is not affected.
I wish that was the case but this is a well known long standing situation...

Is it just from netflix and other streaming apps, because if i stream mkv files to the TV video player (works great ) it does not send trueHD sound to my reciver with arc enabled, but only dolby digital. I have set my dlna server not to transcode anything, just to send the file the way it is) The tv is an LG oled55B7V.

I believe HDMI 2.1 with eARC (enhanced audio return channel) will resolve all outstanding issues that plagued the older standard. I think TVs shipped in 2018 will have it. With eARC the audio bandwidth increases from 1 Mbps to 38 Mbps (8 channels, 192 kHz, 24 bits). That will allow full lossless multi-ch audio to work properly with extra to spare for whatever future audio tech developments may occur over the years.
