This issue is also well documented within the Apple TV community and LG community forums .... https://lgcommunity.us.com/discussion/14247/cx-atmos-audio-bug-with-apple-tv-4k

Because off all my devices are having the studdering problem it does not appear to just be a Roku Ultra 2020 issue

Evidence does point to the LG CX having a problem with DolbyVision and associated audio.  It looks like LG is working on it.

I also had a problem with audio from my SONY blu-ray.  When I chose the blu-ray disc's DolbyVision 5.1 LPCM audio option, I didn't get any sound.  Switched to the DolbyVision 2.0 LPCM option and I got sound.

The most recent LG update was applied last night and now I can get 5.1 LPCM sound from the blu-ray.

I just purchased the Ultra 2020 and have the same issue across all streaming services. I have a Sony 4k tv. When I switch to audio pass through I lose Atmos sound, only reason I purchased this model. 

Also, with this upgrade from my previous Ultra I have lost CEC control with my Anthem Mrx-720 receiver. 

Overall not very impressed with this Roku model and I've owned various models since inception. I will be returning this model and switching to Apple for 4k / Atmos support.

Based on the previous link I posted from the LG community the Apple TV suffers from the same problem.

I've found that the problem may actually be more with the TV.  My my LG TV is behaving better now with the ROKU 2020 and a SONY blu-ray after the latest LG update.  See my earlier post.

Make sure all your components are at their latest upgrade level before returning your ROKU 2020.  Other than the sound issue, I really like everything else on the new ROKU, especially the DolbyVision.

I have no intention of returning the Roku.  As a software engineer myself I realize there are always certain kinks that have to be worked out and I am sure the fine folks at Roku and/or LG will figure out an appropriate fix. I did figure out that if I changed the sound from automatic detection to Dolby Digital Plus, I can watch the YouTube content without studder.  It's just a matter of time.  

 

Worse case scenario I will purchase another https://hdfury.com/product/4k-arcana-18gbps/ and put that in the mix.  I have this on my LG C8 TV because it does not support eARC and appears to work well bit now that I think about it I am not sure I have tested it against sound coming out of Prime channel.  Will test and report back.

Hi Marshal,

My previous response was to mautobot's post.

After the latest LG update, the problems with my Roku and SONY blu-ray have been resolved.

Just wanted to report that even after the latest LG update 03.11.30 the issue is still unresolved. This appears to be a Roku audio compatibility issue.

I am hesitant to say it's just Roke because it is also happening on my Sony DVD player and there are reports on the LG community site that indicates it's also happening for Apple TV

Hi everyone,

Thanks for your patience regarding this issue.

We are currently investigating reports of this issue impacting some LG TV models. In the meantime, we would recommend switching to PCM audio as a temporary workaround.


Thanks,
Danny


Hi Danny, unfortunately switching to PCM for the HDMI port where the Roku is connected has no effect
