You can change the ATV audio output to 16 bit audio, if that is the problem: Settings>Video and Audio>Audio Mode

People that don't know where the beta thread can be found haven't checked the first post.
A lot of people are using tapatalk which can be a pain for certain things. For working within a thread it's good, except you can't see sigs. But trying to find these other threads is a pain.

Yes I use DD5.1 which I upmix to Atmos (see signature.) My soundbar will accept Dolby Truehd so I wanted to point out that Infuse does not pass on the precise formats. I wish my system would accept LPCM, but it does not. Its kind of a dolby only club. I'd be really, really happy if this whole Atmos thing also gets a setting for DD+ output which is an upgrade over DD5.1. Of course I've posted before about having Dolby Access app on ATV4K would allow it to be set to upmix to Atmos which would be an absolute boon for soundbar users.

HDMI Gone Wild - Audio HDMI Chains: (min. upmixed Atmos) Sony X700(Vudu, etc.)
Oppo UDP-203-->LG OLED65B7 and SamsungK950 (4K Atmos discs and files + 2 more subs!)
XboxOneS-->K950 (DTS discs, 2K files, Fandango 2K DTSHD)
ATV4K-->AVRkey-->XboxOneS-->K950 (iTunes and Vudu atmos, &Infuse - dd5.1)
Roku Premiere+-->Oppo UDP-203-->K950(Fandango and MA HDR, DD+)

You seem to be the guy with the answers, found you!

Quick question: I have no issues with my OPPO 203 Dolby Vision playback on my 2016 LG E6 OLED. I have it connected to my Yamaha A3060 receiver, no lip sync problem.

My question is, if my OPPO 203 is using the correct profile for my older LG E6, why can’t Apple TV use the same profile in the settings? Is it in a hidden menu somewhere?

Any ideas? Could Apple remedy this problem by changing their profile in a future update?

Thanks for any input!

What's the problem you're seeing with the E6? I was under the impression it was working as well as can be expected.

I can see links if someone bothers to post them. That’s the key.
And skip to other parts of the same thread if I had reason to believe there was a need to. Though it’s a bit of a pain.
I would have thought all atv talk would be contained in a single thread as it makes the most sense.

@markmanner noted that Vudu is sending Atmos. This is outstanding news because it means:


  • It's easy for third party apps to use Atmos
  • Vudu doesn't have to "re-encode" all their content yet again.

Those functions work I didn’t include links because I’m not doing anyone’s footwork for them. The beta thread has existed for a while and it’s easily found.

Simple really. There is a lip sync issue, where the lips will move on screen about a second after the sound comes out of the speakers. This only happens on Dolby Vision titles on ATV, and not when viewing HDR content. However, I can watch Dolby Vision movies on my OPPO 203 connected to my E6 with no lip sync issues. Also the LG E6 tv apps for Netflix and Amazon video support DV don’t give me lip sync issues either. I wanted to know if the DV profile the OPPO 203 is using can be used for the ATV. Can it be user selected in some hidden menu or is it only changed thru firmware updates?

Also may be useful if Atmos will be limited to UHD/4K like it is elsewhere (Vudu, some discs). Will have to wait and see but good to know. Thanks for sharing!

At this point Atmos is independent of resolution or range. Atmos is being discussed in the Atmos on ATV thread and the ATV tvOS beta thread.

No Disney property has 4K on the ATV in iTunes -- Disney, LucasFilm, Marvel etc -- but some titles may be available if purchased from other providers (e.g. Vudu).

The (currently beta) OPPO 203 software supports Profile 5 and Profile 7 and under typical circumstances the OPPO uses Profile 7 (e.g. you don't have a Sony display). The ATV4K only supports Profile 5. Note that because Robert Z. used the phrase "low latency" to describe Profile 5 it has come into common usage but, since it is the case that a single stream profile is easier to process, one might expect Profile 5 to require a smaller audio sync offset so switching Profile 7 would seem unlike to make anything better.

In any case audio sync is troublesome and chain dependent. I don't have significant issues with DV on either my ATVs or my OPPO. As I've said before app to app (or channel to channel) variances are greater than device to device variances at my house.

Very interesting. I’ve seen it said many times
(Granted, with no reference or backing details) that, from an HDMI standpoint, the AppleTV4K is a “bandwidth hog” and will therefore stress cables moreso than other devices. If this is true, perhaps this additional data that is being sent down the pipe is causing the display device to choke. Of note, the new DV update for the Sony X700 UHD player seems to show the same issue with LGs...

You never mentioned your display, therefore I will assume it’s not a 2016 LG OLED.

Which leads me to my only option; switching to HDR 60Hz video output on the ATV for all content to avoid DV audio sync issues. And for DV content I’ll stick with my OPPO 203 which plays DV perfectly, no sync issues. I still don’t get why ATV switching to profile 7 wouldn’t solve the issue, unless there’s something else magical going inside the OPPO 203 that doesn’t cause DV audio sync issues.

I’ve heard the newer 2018 LG OLEDs have the newer A9 alpha processors which should solve a lot of problems, but I’m not upgrading my E6 until HDMI 2.1 hopefully next year.

Thanks for the input.

Because audio/lip sync issues being discussed here are caused by video processing - the more a device in the chain after the player has to work on the video stream (decode it, interlace it, de-interlace it, scale it, etc) the more the video will be delayed (assuming the device doesn't have sufficient processing power to handle it). Profile 5 is designed to require less work by the display device because the player/source device is doing some of the work. Under Profile 7, the display device will have to do the same amount or more work. So if a display device is already having trouble processing Profile 5, then it's going to be same or worse with Profile 7.

I have an Anthem AVM60 and Sony 940D using Roku ultra 4K streamer! Several weeks ago my Roku ultra started having audio dropouts intermittently. Not happened before ! After trying rebooting and many other things ... nothing has changed . I think I want to change to AppleTV 4K streamer. Before I do is there any major issues with it that I need to be aware of? I stream on Netflix , Amazon Prime , Hulu , You Tube, CBS all acess. No issues with any of those apps that anyone knows?

All those apps work fine but YouTube is capped at 1080p.

I don’t use all the apps you ask about, but the main gripe with the Amazon app is they don’t provide 5.1 audio for all their original content shows. It’s hit or miss and frustrating.

I haven't measured it, but I don't think the volume on VUDU movies is as low as what I experience with iTunes movies.

System
Spoiler!

HDMI drivers and receivers are essentially fully specified. All compatible devices send equivalent data for the same source material. Incompatible devices fail to reliably exchange data -- this is typically quite obvious.


I've seen one (or so) annecdotal report about the ATV4K being fussy about cabling. I don't have that experience. The only 4K source I've had any issue with is a TiVo that grew unhappy with its (non-Premium Certified) cable after a few months of use. I used the same cable on an ATV4K without issue but I replaced it as well out of an abundance of caution.

I might type 2K for 1080p.

I’ve heard the newer 2018 LG OLEDs have the newer A9 alpha processors which should solve a lot of problems.

I have a C7. It's listed in my signature. The sum of your comments appears to be that the E6 is not at fault but the better 2018 models will solve the problem and since I'm not having the problem I must not have a 2016 LG.

I don't believe audio sync issues are specific to Apple or that Apple bears a greater burden to resolve them.

I might type 2K for 1080p.
