New LG CX OLED Audio skipping

Another solution that seems to work is to open Amazon Prime App (On AppleTV) and Play a video from there. it changes the Audio Format and Fixes the Bug without having to Restart it. Having said that this is not something Unique to AppleTV i'm also having this issue with my Xbox Series X. Don't know the sequence to triggering it as has been working flawless for last 3 weeks until last night. Again on did not even realise as was wearing headset ad TV volume was very low until someone told me why is sound weird. Will further Investigate but LG really needs to look at this. Not even going to go into Sound Delay with Optic Cable

YES, has solved both Issues, Including Xbox. So Happy. Having said that, did you get from the AppleTV as it were connecting to a New TV? I got the Try Dolby Atmos Screen again. It also reset the AppleTV Settings for that specific TV

Just got the US CX 77” a few days ago and noticed the problem when trying to watch 4K content via YouTube app on Apple TV. I’ve tried many recommended solutions and only temp fix is to restart TV. Thanks to all that have been posting and looking forward to update.

Unfortunately, after writing with LG® support, I have bad news. They answered my question for the update that resolves the issue we all have:

————————————————————————————————

"(...) Aktuell liegen uns keine Informatione vor bzgl. eines Updates für den von Ihnen genannten Fehler. 

Mögliche Ursachen können aber auch beim HDMI Kabel liegen oder aber bei Apple TV selbst. Vielleicht hat evtl. Apple ein Lösung in Form eines Updates. (...)"

Translation:

(" (...) Currently we don't have any information concerning an update targeting the issue described by you. Possible causes could very well be the HDMI cable or the Apple TV itself. Perhaps Apple has a solution in form of an update. (...)"

————————————————————————————————

So far there is no released update for my "LG® OLED 55 CX series™" when I have my TV search for it.

This topic is very annoying, as it is clear:

• It is very unlikely that the HDMI™ cable could be the source of this issue as a hardware configuration does not change by restarting your TV and this is the only action that solved the issue temporary until after watching the next Dolby Atmos™ content.

• A restart of the Apple TV without unplugging the power supply of the TV does not bring an end to the audio distortions. Accordingly it is extremely unlikely that the Apple TV is either causing the issue nor that a future update on the Apple TV will have any positive effect on the issue.

• As many have reported that their LG® TV has recently received an update and it has permanently resolved the problem, I am wondering how LG® support could act as if this whole topic is brand new to them or as if it was only an issue of one single setup and not every customer connecting certain Dolby Atmos™ ready TVs to an Apple TV or BlueRay™ player as mentioned multiple times here.

3.21.09 doesn't fix it for me. And this is an LG issue (Xbox Atmos is has the same issue).

device e-arc to CX to soundbar (any).

This seems to have been introduced a few firmwares ago (after June 2020) when LG fixed the initial LPCM issue. Atmos has been experiencing dropouts for me since.

I first thought 3.21.09 fixed it, but it was short-lived - and probably just the cold boot it required the TV to do.

The fix isn't documented in the notes about the fw either. Super frustrating.

It is just unbelievable how bad support works! The misinformation they manage!

I had an answer from the technician after him talked with LG here in France, saying that an update solving this issue was in the making and it got released so YES did solve the issue.

So if I am you, I will answer them saying that before send an answer and blaming others, to get informed because in a country called France, LG the company they work with said that was an update in the making for that! That update is already out and solved the problem!

I’m experiencing the exact same thing 2019 LG OLED 65”. Tried everything nothing works, audio continues to skip and go out, it’s so annoying. Tried 2-Apple TV 4K’s, new HDMI Cable and Soundbars. Have appropriate audio settings, turned off Dolby Atmos, etc as suggested no improvement.

This is definitely an Apple software issue. Apple Support, are you reading these posts or do you give a care. Stop recommending we perform a reboot.

Apple You have the money and staff to rectify this issue for your customers with a simple request for the AppleTV team to release an update ASAP. This is ridiculous!

Support you need to give us a status update on how you plan to rectify this issue hundreds of your customers are experiencing.

I’m experiencing the exact same issue. Audio continuously skips in and out and sometimes Dolby Vision flashes on my screen. It’s so annoying!

What’s taking Apple Support so long to release a fix. Tried everything within config settings this problem is only happening with my 4K Apple TV.

Support can you at least respond to all these numerous threads of complaints with some glimpse of hopes for remedies you’re working on for your customers..

As of March 2021,

There is now a software update for the LG tv that fixes this.

to update: Settings, All Settings, Support, Software Update. It’ll take a long time.

the work around mentioned before work, in addition to just disabling the Dolby Audio (until the software update is complete of course cuz you PAID for that feature!)

I am having this same exact problem and this makes perfect sense to me. I have not had the issue until switching from some content to other, so this makes perfect sense.

Apple please fix this.

1.     Restart Modem.

2.     Restart Router

3.     Unplug Apple TV from Power for 2-3 minutes – re-plug in and retest. 

Same issue, same TV except the 48in model. I was losing my mind attempting to troubleshoot. Thank you.

I’ve had this same problem but it’s also effecting my picture as well, the screen will flicker and keep changing from Dolby vision

Yep another one on the list with an LG 65” CX and the loss of sound after Atmos. This is starting to sound like it only effects the OLED’s.....🤷🏼‍♂️

I run it with a Samsung Soundbar from a former TV. Still has the same problem. I have an earlier post on the thread.
