I am new to Vero V and OSMC, but not new to Kodi, been using it for years. I do have a relatively new HT setup, and having a difficult time getting audio to sync with video. I have gone through the gamut of turning off the Denon built-in lip sync, turning off and on the sync in the OSMC settings, setting passthrough off and on, changing the display mode on the TV from Filmmaker to Game, setting the display processing to bypass in the Denon, etc, and just about every mix and match permutation of all of these combined. This occurs on low-res video with 2.0 channel audio, and 4k UHD HDR + Atmos files. If I can get it close on type of video, it is worse on the others. What am I missing here?
Can you provide a sample?
Do these same files play without sync issues on some other player?
What’s your source path (Vero V → Denon → LG OLED)?

I’ve got the same set up and have no issues with lip sync on the Vero, gaming is another matter. Passthrough on TV, lip sync set to auto on avr and no delay set in Kodi work fine for me .
What passthrough are you referring to on the TV? Audio passthrough? I have audio passthrough enabled on the TV, but that should only matter when playing content directly from apps on the TV, not the Vero V, right?
I originally had Kodi side-loaded directly on the LG B4 OLED tv, but every time they pushed an update, it would delete the app, which is why I went with the Vero V for a dedicated device. When it played on the TV, there were only a very few intermittent files that had audio sync issues, but most played just fine, going from TV App => Denon AVR-X3800H through eARC.
Now with the Vero V, it started that I really only had issues with files that had DTS codecs, they would consistently be desynced, but Dolby codecs were fine. But the last week, it seems like everything has gotten out of whack. 720p with AAC 2.0 tracks are off-sync, as well as a UHD 7.1 Atmos w/ Dolby Vision, and everything in between.
My source path yes, is Vero V => Denon AVR-X3800H => LG B4 77” OLED. All connected through 8K capable HDMI cables.
Have you tried doing a soft reset of your Denon AVR? I have to do this to mind every once and awhile when it starts misbehaving. You should just need to hold down the power button for a number of seconds until you see lights start to change and hear the relays inside click. This “soft” reset does not erase any of your configuration but it does do something more than just pulling the power cord.
Just to add to this, I’ve got a vero5k in to a Denon 4800h (in a 11.2.4 set up) in to a Samsung q9fn. Recently the sync has seemed to be roughly 100ms out (audio in front of video) across dts and atmos tracks (more noticeable In DTS) It never used to be. The files play fine elsewhere.
The TV hasn’t had any firmware updates (it’s old, not connected to the internet any more etc) the denon hasn’t had a recent firmware update either. The only thing that has recently updated is the vero5k from the November update.
It’s not consistently out of sync either, it’s quite strange.
Happy to help debug what this could be.

Can you give us:
- A sample file or known clip that causes this issue
- A description of you how have ascertained it’s 100ms out (I don’t disbelieve you, just need a metric)
- A log of a file you play that’s affected
Cheers

Hey @sam_nazarko ,
For the 100ms - was mostly just eyeballing the delay during playback. I honestly don’t know if it’s 100ms out but it made it “feel” more in sync. Especially during fast paced talking etc it just seemed to fit better.
I can provide a log tomorrow for a file - it does appear to be more the DTS tracks rather than the Atmos tracks that are being impacted (or at least to my eyes! but honestly it could just be my brain 
)
Hi
Did you have a chance to upload a log so we can check this out?
