HW-Q90R Lip-sync issues

SIR-Blade — Mon, 14 Oct 2019 10:14:04 GMT

For you guys who are having LIP sync issues, I've solved it by connecting my Blu-ray player direct to the Soundbar, rather than the TV.

SET-UP.

Blu-ray player = LG UBK90

TV = LG OLED55C9PLA

Soundbar = HW-Q90R

Initial connections. Blu-ray to HDMI-1 on the TV, and TV HDMI ARC to HDMI Arc on the Soundbar.
All sound types other than Dolby Atmos have NO delay problems. When DOLBY Atmos used, i.e. using bitstream input, and auto decode, or any other option to enable Dolby Atmos you get a delay or around 120ms between screen and sound.

Intuitively you would think this should be the connected setup, so with all delay options on soundbar and TV set to Zero, you can't go negative numbers, you will always get a delay. Obviously decode processing times cause a delay within the soundbar.

Changing setup of Blu-ray to HDMI-2 on the soundbar, and keep HDMI ARC on soundbar to HDMI ARC on TV, you get NO delay with Dolby Atmos, as the Soundbar is doing the decoding and sending the video data at the correct time, in this case again with a Zero delay setting on the soundbar.

You are losing Blu-ray to tv connectivity, but most systems can communicate fine through the soundbar with CEC codes anyway, and picture quality should be the same. It's digital init ?

Ideally, I'd want the Blu-ray player connected directly to the TV, but until Samsung sort out delay processing issues, then outputing directly to soundbar is the only work around.

Forgot to mention. I've firmware patched it to the latest version, i.e. 1008

Is there any solution if someone don't use Blu-ray player but streams the Dolby Atmos content direclty from the TV via built-in Netflix app?

I have a question regarding your remark: "you can't go negative numbers". I have noticed that, but I am guessing that this could fix some of my sync issues. Is this something that is not technically possible, or it is not implemented.

I know this possibility for example exists within VLC Player.

Interested to see your response.

SET-UP:

Streaming device = Apple TV 4K with Netflix App

TV = LG OLED65E8PUA

Soundbar = HW-Q90R

I just got my Q90R this weekend. I have pretty much the same connections as SIR-Blade except I have an Apple TV 4K attached to HDMI1 on the TV. I upgraded the soundbar to the latest firmware and I'm using the HDMI ARC connection between the soundbar and TV. I'm having lip-sync issues with Atmos content being streamed from Netflix on the Apple TV. I'm assuming if I plug the Apple TV to the HDMI2 connection on the soundbar this problem should go away. Is there an option to tweek the delay in settings somewhere or any other options to try?

My problem was a little different than the problem mentioned above. Programs through cable were all out of sync and the adjustment, like everyone else, didn't work as the sync would not go into negative numbers. I was able to avoid the problem by inputting the cable hdmi directly into the soundbar. I haven't had the problem of lag from my blue ray player to the tv to the soundbar.

Hey everyone! Just got a C9 (wow) and a Samsung Q90R Soundbar to go with it. Best lockdown ever!

Until...I immediately noticed lip sync lag. On basically everything. Internal apps and external connections.

Video is slightly behind audio. The closest I’ve got to it being right is:

PS4 pro + LG 4kplayer to HMDI on Samsung Q90R> then HMDI Arc to LGC9.

But as good as The Matrix looks in 4K, Trinity’s lips are just a little slow... And flashes are behind etc. and when you see the dialogue delay. You can’t I see it!

I don’t want to be dramatic but actually lost sleep over this after spending more money than I’ve ever spent and really needing the relaxing comfort of losing myself in some films...From Endgame on Disney+ to Endgame on UHD Disc...it’s just ain’t right.

I spent a night digging through all these forums and Dolby seems to be the issue? But don’t really want to go back to digital optical 5.1 and lose all this Atmos etc. so close but yet so well, 10ms far.

Has ANYONE solved this? I’ll be eternally grateful.

Had the same issues...I wish the reveiwers had mentioned problems when I spent days combing through reviews to get a great system. I found by going through the soundbar directly it alleviated 95% of the problems.

Thanks Lowell882... So you feel my pain! When you say solved 95% of the problems, do you mean got everything a little bit closer to being in sync? Are you sticking with it? And hoping for a firmware update fix?

Let's just say I don't watch everyone's mouths anymore and the wife stopped complaining. Once in awhile it is still off on certain channels where I notice it. Samsung needs to provide a software update as you can adjust the sync only in one direction and of course that's not the direction they provide. I'm still amazed none of the reviewers mentioned the problem....pay high end prices and you would expect high end performance.

How are everyone's lip sync issues after the new eArc firmware update for the Q90R soundbar?

Hi. If you connect a device like a Sky Q 4K box through the Q90R soundbar instead of the Samsung TV's one connrect box, even though it fixes the lip sync issues? does it affect picture quality at all?

First time poster, I wanted to follow up on this to possibly help others. I'm not an A/V genius but am fairly adept, I'm kind of embarrassed it took me this long to figure out. (Ok, finding this forum definitely helped give me some ideas of what to try!)

After months of what seemed like hopeless sync delays over broadcast TV (got my system in early February just before COVID-mania set in), I made this change (OTA box in to sound bar via HDMI instead of directly to the tv) and the problem is gone. I never had trouble via streaming or Blu-Ray, only broadcast tv (via TiVo Roamio box) and things have never sounded better. Blu-Ray still goes directly to the tv and seems to be fine via ARC.

This is probably "duh" territory for a lot of you that are above and beyond my outdated knowledge on this kind of stuff...like I said, I'm not a total Neanderthal when it comes to this kind of stuff and wanted to mention it just in the event that it helps any lightbulb clicks. Especially for us old RCA cable type of folks!

I am making an assumption here, but with a cable box or antenna passing through the sound bar, I can't imagine that any video signal loss would be an issue, especially if it's a trade off to the lip sync issue. Now, 4K sources may be another story?

Never been happier with my system, am hoping Samsung solves the intermittent random shutting-off issue in the near future as this has been my only other real annoyance. (Issue described elsewhere, HDMIs need to be unplugged and inputs need to be reset)

Not getting lip sync issues with mine. And got my Xbox one X directly to sound bar and atmos runs with lip sync issues.

Is all in sync for me.

Re: HW-Q90R Lip-sync issues

denodan — Thu, 28 May 2020 03:55:15 GMT

No issues here with atmos and xbox one x and going straight into hdmi 1 on sound bar. Mind you also have a samsung q90r tv. No lip sync issues for me

Why are all you guys having lip sync issues?

Not getting issues with my gaming or Netflix on my q90r tv and q90r soundbar and running dolby atmos.

Got xbox into hdmi 1von the soundbar not through tv as I wont get dolby atmos through tv anyway even with soundbar on, got to directly go through soundbar.

I found how to fix lip sync on the Q90T TV. I'm using a Q70T sound bar. Plugged Blu-Ray player into sound bar. Sound bar into arc port on tv.. Cable box, PS4, Nintendo Switch/classic NES (switcher) in the other three tv HDMI ports. Blu-ray worked fine like this. PCM worked for the others. Then I enabled eArc on the tv. And more importantly I selected audio pass through. The sound from the devices connected to the tv now pass through the tv unaltered and get decoded in sync by the sound bar. All devices now using bitstream and have Dolby turned on now. Not sure if pass through is an option on the Q90R tv, but that's the solution on the Q90T
