- The 3:16 Drop out Only happens when Bitstreaming and happens in both Title and Menu mode.
- There is No 3:16 Drop out in either Title or Menu mode when Decoding.

I tried to reproduce this, but I don't have an Atmos AVR, and on my ordinary TrueHD AVR there is no drop outs here.
I can also not spot any obvious problems in the data flow around those times. I would imagine a fundamental problem *should* also show up with normal TrueHD bitstreaming, so who knows whats wrong there.
TrueHD bitstreaming, especially with Atmos in the mix, is still a black box. That I managed to resolve the issues with high-bitrate UHD TrueHD tracks earlier was already pushing the limits of the informaiton that are available about the process.
Without at least access to hardware showing the issue, or a full specification of how its supposed to work, there is probably nothing I can do.
Maybe in a year or two, if I should decide to invest in a new AVR, and proper HDMI 2.1 models become available.
Edit:
I did some simplifications and cleanup in LAV Audio, and I think there might have been a small corner case that might have been fixed by this. I'm not 100% sure since the dataflow is rather complex, and I could never reproduce the problem in the first place.
Anyhow, if anyone with an Atmos receiver feels like testing, grab the next LAV nightly that should show up at around 3:00 AM CET at https://files.1f0.de/lavf/nightly/ (you're looking for 0.73.1-1)
jmone:
Thanks for looking but unfortunately, no cigar. Still get it. It really is not a "Hard Drop Out" like we used to have, in that the AVR is still reporting that it is getting an audio stream but instead it is a short silence. This happens at the point of the seamless branching where at 3:16 it goes from the interrogation scene to the rotating Incredibles logo (which can be in a few different lang). It's almost like there is a timestamp issue at the seamless branching point.... but, what gets me, is that if you do a seek after passing 3:16 to before 3:16 there is no issue as you pass 3:16 again.
SamuriHL:
Yup, that's exactly right. And I don't understand it cause the symptoms are different with non-LAV solutions like the SHIELD. It gradually gets out of sync. So there definitely seems to be some kind of seamless branching issue but no idea how we can fix it as every single ripping tool shows the same issue.
jmone:
FYI - I went back and tested using "LAVFilters-0.71.0-35" from May 2018 (I think this was before the hard drop out fix but post much of the UHD support work). Good news is that this version works fine on Incredibles 2 (but of course will have the hard drop outs with other titles) but it may help track down the issue.
Hendrik:
Did you ever test the Windows 10 "Films & TV" app to play back this title? Possibly need to try it with a MKV rip, since it cannot play Blu-ray discs.
It supports bitstreaming TrueHD from what I can tell, as long as the HDMI out is the default output in Windows.
If it works, maybe I can figure out how it works.
