New LG CX OLED Audio skipping

Got a new LG CX OLED 55 inch yesterday. I hooked it up to my 4th gen Apple tv. Now picture quality is great, but my audio keeps cutting in and out, like it stuttering. I bought a good quality HDMI cable and have since actually tried several HDMI cables and they all do the same thing. I also tried all 4 HDMI ports on the TV same result. If I use the build in app on the TV using WEBPOS they are fine no audio issues. I have tried every option in the TV for sound and in Apple TV same issue. It's like apple TV isn'y able to keep up with the audio or something. Any idea what would cause audio to cut in and out? I posted over at Apple TV reddit but no one has a clue LOL, seems like I am the only person having this issue. Running the latest official version for Apple TV didn't work also downloaded the latest beta version that didn't work either. If you go on Reddit apparently there is a ton of people having the same issue with Apple TV and this LG TV. pretty sure it's an Apple TV problem though because all my other streaming devices work perfectly fine with the LG TV.

Apple TV 4K, tvOS 14

Okay I pretty much figured it out. If you watch any video that has Dolby Atmos sound that's when it's going to screw up. So if you watch a video on Netflix that has Dolby Atmos sound you'll be fine. As soon as you exit out of that and say launch a video on YouTube or any other video type app that isn't Dolby Atmos enabled that's when the audio will start skipping. Somehow when you try to play a video that isn't Dolby Atmos enabled after just watching one that was it screws up the audio. So what you have to do is basically restart the Apple TV turn your TV off then turn it back on and then you can watch anything that isn't Dolby Atmos enabled and the audio will be perfectly fine. You can go into Netflix again and watch a video that has Dolby Atmos sound but once you're finished you have to restart your Apple device turn your TV off and turn it back on then normal audio will be fine. so anytime you see the Dolby Atmos sound Logo Pop up in the top right hand corner you'll know that when you're done watching whatever you're watching you'll have to restart Apple TV and your TV unless you're going to another video that is Dolby Atmos enabled then you'll be fine it's only when you go to regular audio that it starts to screw up. I know this isn't a fix it's more like a Band-Aid. But the problem definitely is software based and it's from the Apple TV. none of my other streaming devices and I've tried almost all of them do this only Apple TV. If others are having the same issue you should try what I suggested and try duplicating what I did. I'm going to send this off to Apple tech support as well

I’m fed up with this now...the ATV and my CX worked just fine for a few days, but today we were watching shows on Netflix and decided to watch a purchased movie through iTunes. The sound kept skipping. Restarted many time. No change. I said f-it and grabbed my Roku. Guess what? It worked just fine with zero issues. I’ll stick with my Roku and my CX now. Don’t tell me it’s an LG issue.

Same skipping audio issue here after watching Atmos for me. LG65cx and Sonos arc soundbar using eArc.


switching atv and lg tv off and on rarely works to fix it.


The only semi reliable fix for me is after watching an atmos show, switching sound format on the ATV to change to Dolby digital 5.1, watching something else for a few seconds then switching back to best quality (Atmos).

Hello, the AppleTv has nothing to do with the issue, it happens also with my Xbox Series X, it comes from the LG Tv confirmed by a technician that changed the motherboard in my TV and also by the LG Service.

They are working in a firmware update that will solve the issue. A moderator form an LG forum said that is expecting this month, so let’s hope is soon. 👍

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

Hi, just to give some info because I have the same problem, after doing lots of tests, talked with technicians that they were very positive about the problem coming from the Apple TV, finally the problem is not the Apple TV, it comes from the LG TV, it happens with others devices, in my case with an Xbox.

LG is preparing an update that it looks it will fix the issue, but it starting to get a little long, I know this because the LG technician communicated me to tell me that.

Is a very annoying issue and it drives me nuts, doing some tricks is possible to get the sound back normally but sometimes it comes back after the TV is being shut off for maybe 1 hour.

So lets hope the update comes soon.

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 switched back to running everything through my receiver and it fixed the problem.


I have a Pioneer VSX 302 which supports DV and HDR, the only reason I ran everything through tv was I heard there was input lag for gaming but really I don’t notice and will keep it this way


not really helpful for you sorry, but just responding- hopefully it’s fixed at some point

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.
