ARC intermittent connection loss possibly with Atmos only

Hi all. So far I think this is isolated to Atmos content however randomly while watching Prime Video or Disney content outputting Atmos (through fire stick 4K) I will lose signal (Beam gen 2 and two one sl’s as surround). When it happens I lose sound, the screen flashes and my tv’s LG logo appears for a second before going back to Disney or prime (whatever I’m watching). I can push play and everything works again, but almost seems like something with the HDMI arc input is being “lost” for a split second. Or maybe it’s the signal loss for a split second?

I’ve changed HDMI cords and powered down both the tv and Beam to try and reset but no luck. Randomly happens, sometimes 5 minutes in and other times maybe 15 in. Any ideas?

fyi I recently changed to using SonosNet (beam hardwired Ethernet) as opposed to all wireless is this possibly an issue that anyone knows about?

Setup as follows:

Well gentlemen @Ken_Griffiths and @ThatOneDude I think I am marking this as resolved. Made it through the entire Disney + Atmos movie, and now running through an Amazon Prime Atmos show just to make sure but all is working as advertised and nothing cutting our nor any lip sync issues. My System and settings are as follows:

System: LG TV with a Firestick 4K in HDMI 1, Sonos Beam (Gen 2) in HDMI 2 (Arc) both connected via HDMI.

LG TV Settings:

HDMI: ARC

Digital Sound Out: Auto

HDMI Input: all inputs set to Bitstream

Firestick 4K Settings:

Video Resolution: Auto

Match Original Frame Rate: Off

Color Depth: Up to 10 bits

Color Format: Auto

Dynamic Range Setting: Adaptive

Surround Sound: Best Available

A PCM audio setting should get rid of any lip-sync issues. as it’s the default stereo output for all TV’s and is recommended if the TV is old and it’s processor slow and cannot ‘pass-through’ the audio.

Personally, in those type of cases, I would recommend the user opts to use an audio-extractor instead and bypass the TV altogether. There are three common extractors mentioned in the community here for those that have lip-sync issues due to the reasons mentioned, the extractors are:

HDFury Arcana

Feintech VAX04101A

OREI HDA-931 or OREI HDA-935

Hey @Ken_Griffiths Do you have any US equivalent that you suggest? I noticed that although Prime and Disney etc are working great, I do have a little bit of lip sync on YouTubeTv only and only when the content is being streamed in DD 2.0. I see I can get the HDFury but the reviews arent great. Any other suggestions or do you think that should do the trick since I am using a Firestick 4K?

Or is that more than I need since I am already getting Atmos content? Is there something else that I could get that would help with lip sync? When I change the setting through the Sonos app it works, but then I am off again when going to DD+ content

Thanks again for all of your help!

My old TV in the Dining Room is ARC only, not eARC, and this chart shows the audio-bandwidth differences between the two types of Port:

Anyhow, my TV has quite a slow processor and no audio pass-through and that’s why I purchased an audio extractor (Feintech VAX04101A) to provide the option of bypassing the TV with external devices like FireTV etc. Such extractors do all work well, but are quite expensive, but much cheaper than buying a new TV and apart from anything else the TV in the Dining Room was otherwise a nice TV (just a bit old).

Anyhow, the extractor/switch worked great and it solved all the lip-sync issues I was seeing with the connected devices/apps and gave me DD+ Atmos (compressed) audio capability too… It actually supports the multichannel Linear PCM (uncompressed) audio codec aswell as Dolby Digital TrueHD (Atmos) (uncompressed) audio, not that I use those two codecs on that particular setup.

I have heard a lot of good reports from users about the devices and I understand the Arcana is very good aswell .. the OREI device is the ‘new kid on the block’ and I’ve seen good reports about that too. So my thoughts are there is perhaps little to choose between them except the case that the OREI and Feintech devices are a combined extractor/switch, whereas the Arcana would require you to add a HDMI switch, that’s if you needed to plugin more than one external device, like FireTV and say Apple TV, as an example.

The Arcana is also the more expensive product.

So my thoughts are to perhaps do a little more research to begin with and think about your longer term needs and then make your selection, but if it comes down to the Arcana or OREI device (because you perhaps cannot get your hands on the Feintech device) then I would personally go with OREI, but sadly I can’t ‘truly’ vouch for it, as I’ve never used it (or the Arcana for that matter).. it’s just the fact it’s a combined HDMI switch that makes me sway towards that product.

I understand HDFury do have an Arcana-combined-switch device called VRRoom, but it’s apparently very expensive and I’ve not yet come across anyone who uses that product, but here is a link to perhaps assist your research:

I hope that info. helps 👍

I’ve purchased both the HD Fury Arcana and the OREI devices here in the states, one from HD Fury directly, the other through Amazon.

I just pulled the trigger in the Orei HDA-932. How do you like it? Hoping it will fix my lip sync issues. I think my tv processor is just not ideal to handle Atmos content all the time for my Sonos Beam (Gen 2), Plus the tv is only ARC, not eARC. Delivers Friday!

Just wanted to let ya know @RaultTN that so far I havent gotten a single cut out which I find amazing. Never did I think to set the Digital Out to Auto because everything I read always said Pass-through. Also I havent noticed any Lip sync issues on my end. Thanks for everyone's help! May we all have many a night of undisturbed media viewing. 🍻

Crazy right? Same here, never thought about it because everything says to stick to pass-through. I also just realized (like 5 minutes ago) I had my “Instant Game Response” turned on for HDMI 1 (firestick) as opposed to HDMI3 (xbox) for some reason. This is the reason I was having a slight lip sync on YouTube tv. I’m gonna check out this Orei anyways to see how I like it but man what a mess the last week has been trying to figure this out haha. Glad it worked for you also!! Cheers!!

Haven’t had the time to install it yet. There’s a need for wrangling which one connects to which TV, and I’ve been somewhat busy.

When you do setup and have the OREI working Bruce, I would be interested too in what you think about it in comparison to the Arcana .. no rush of course.👍 (TIA)

Gentlemen @Airgetlam @Ken_Griffiths @ThatOneDude. just got my Orei 931 and have a question about setup. Correct me if i am wrong:

HDA-931 Front:

HDMI In: Firestick 4K

HDA-931 Back

Soundbar eARC: To my Sonos Beam Gen 2 ARC

TV HDMI: to my tv (HDMI 1). If I plug into HDMI 2 I don’t get sound? should it to go into the ARC input? Does it matter? Maybe my settings need changed from my end?

Cool! Well from what the paper says, it seems correct. I heard that the HDMI OUT that goes to the TV SHOULD go into the eARC/ARC one to use CEC controls.

Yea I think that is right. Just gonna have to figure out what setting I have that is not allowing sound to come through.

Do y’all know if there is an advantage of using a firestick over the apps on a smart tv? Is it primarily UI or are there audio/video advantages to one or the other?
