New LG CX OLED Audio skipping

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!)

Same issue here. LG OLED CX 55 inch, Apple TV 4K. Had to turn Atmos off completely on Apple TV to prevent this, which is disappointing since it sounds amazing when enabled. Behaves the same regardless of whether my sound bar is attached or not; same glitches with built-in speakers. Apple tvOS update that solves this will be an amazing Christmas present.

I have this exact same problem and find that powering off the TV will work 75% of the time. Sometimes, however, it takes me unplugging the TV from the wall and doing a full power down. This latter option has fixed it every time. It is a real pain, especially for my wife and children who aren't able to perform these fixes. It makes little sense to them.

I am glad to hear I am not crazy. I was about to attempt a replacement of all my HDMI cables. I was also worries that it was my new TV.

Devices used: LG® OLED 55 GX9LA, TV 4k, UHD HDMI cable

I can confirm the issue on my setting. After watching for example Netflix with Dolby Atmos™ content I experience rhythmical audio dropouts every 4-5 seconds for about 1 second each. When connecting a Bluetooth® Headphone to the TV, the bug does not take effect. So it can be narrowed down to an issue with the audio that is sent via HDMI.

A complete restart of the TV solves the issue while a restart of the TV doesn't.

Nevertheless it is an issue only affecting the input from the Apple TV, not the BlueRay™-Player. This doesn't really help as the issue seems to be connected to switching back after playing Dolby Atmos™ content. Could be the TV having issues with that or the TV.

However, this issue is really really annoying and disturbing the user experience immensely.

If it can't be nailed down to on of the devices, Apple support should get in contact with LG and maybe other affected high end TV producers to solve this in an upcoming software update.

In my case, ATV 4k and LG SN8 soundbar are my equipment, I was watching Mandalorian (Dolby Atmos).

Restarting &/or powering down TV, ATV, Soundbar did not resolve it, but power down, then **unplugging** the TV solved the problem. Every time I watch Dolby Atmos on ATV, I need to unplug the TV to resolve it.

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.

GOOD NEWS!!!

The new LG TV firmware update 03.21.09 has resolved the issue, at leatfor

me, hope for the rest too!

I will do other tests with Xbox also but it looks fine!

Mine updated to 03.21.09 this morning, can confirm it fixed the issue, also reset the Apple TV settings as mentioned by others so check these. I’m in UK.

3.21.16 seems to have fixed mine. Don’t know if it’s any different from 3.21.09 or whether it’s just different numbering for different reasons

I’ve had an issue there’s a lip sync delay what solved my issue was go into Apple TV settings under audio and video and turn off 4K Dolby and select 4K hdr instead ....fixed the problem

Thanks for this, just got a new LG OLED 55 and was having exactly the same issue you describe. Switched HDMI inputs around and changed audio settings on Apple 4K to no avail. Only complete down power of both LG TV and Apple TV appears to have resolved the issue as a temporary work around.

Wow, am I ever glad I found this thread! I was having the same skipping audio problem with Apple TV hooked to new LG CX 48 Oled.

I have both TV and Apple TV puck plugged into same switchable power strip so turning strip off & on is now my fix.

Prior to that much frustration including purchase of new 8K HDMI cables from Monoprice that didn’t fix.

Thanks to all for sharing. Hope there is a future software update to address this inconvenience.

Same issue here as well but with the 65" GX OLED. One workaround I have found that works for me: find a program that is 5.1 from netflix (usually something from my "Watch It Again" list) for a few seconds and the dropout is gone. Super frustrating from the most expensive streaming box on the planet!

No help to anyone, but I have this problem too. Apple TV 4k and LG OLED CX. Turning the tv off and on doesn’t fix it every time for me, so I do what someone else mentioned here, play something in Netflix for a few seconds (5.1), which seems to reset it.
