That was my thought after getting the new samples with sound. Perhaps I'll make a new thread in the audio section. Thanks.

There is no need to upload new samples. The original one I shared before works just fine on ShieldTV (bitstreaming Atmos) but hit dropouts when playing on Windows with Lav+MPC-HC or DSPlayer.

Which is exactly the same behavior I'm seeing even with the new rip I did.

Hello!I can finally run high bitrate 2160p() but...
Do I lose picture quality running D3D11(native) instead of D3D11 copy back?Wanted to try copy back but when I set hardware device it returns to automatic.
GPU:RX 470(polaris)

No quality loss with D3D11 native.

Dobly truehd tracks with 7.1 channels muxed in mkv are displayed as "7.1".
Dobly e-ac3 tracks with 7.1 channels muxed in mkv are displayed as "8 channels" instead.

See attached picture:



This is not an issue of matroska, as it only stores a single number for the total number of channels (2, 6, 8, etc) and not the layout.

The layout information is something that lav filters find, probably by bitstream parsing or something. But whatever they do, it's not done for the eac-3 tracks.

This is purely a cosmetic issue, but would be nice if it could be fixed. Thanks.

I wouldn't expect that to change, really. Determining the proper channel layout for Blu-ray style eac3 is kinda complicated, and its plenty that the decoder knows how to do it, the demuxer really doesn't need that info, and it would be complex code to add for cosmetics.

Make sure you watch from the beginning. Most of us see an audio drop around the 3:17 mark, but not if you just skip to somewhere close to it (which could give a clue to what is causing it - a buffer issue?)
I check playback in MPC-BE on my A/V receiver(it's support TrueHD but don't support Atmos extension) - and have no drop. Play from start for end of sample.

Yea, it's without a doubt an issue with the ATMOS extensions. People who've decoded to PCM report no problems, as well.

I'm test on bitstream - no drops.

Bitstreaming the TrueHD only or ATMOS? Cause it matters.

Yup...and as I said before, it's only bitstreaming the ATMOS extensions that shows the issue.

Test only the TrueHD piece is not enough to reproduce the problem. You need an Atmos capable receiver to reproduce it.

I tested the Incredibles 2 file bitstreaming Atmos (Denon X8500H, see my sig). No drop. MPC-BE+LAV latest.

You might need to list your software + AVR to narrow this down, because not everyone gets these drops.

My software is J River MC. And I definitely get drops on my Pio VSX-303 receiver.

You could try with MPC-BE (using latest external LAV) and see if you still get drops. If not, that would rule LAV out and you could ask jRiver to fix it.

I’m not saying you are not getting drop. I am saying that not everyone does, and that here LAV works fine with this file. See the rest of my config in my sig, anything else could be a contributing factor (including OS or GPU driver version).

If everyone having this issue posts their detailed software and hardware config, it might help those affected to find the common denominator. If Nevcairiel can’t reproduce, it is unlikely to get fixed otherwise.

You can try MPC-BE without using LAV.
