Atmos issues

Does me too mean you still have problems or issue has gone away?

Have sent you PM for new video stack.

Toy Story 2 still glitches, audio.

Since Toy Story 2 4K seems to be a problem, I’ve order a copy for myself so I can test. It will be here Wednesday.

I’m curious, has anyone who’s having problems with Toy Story tried Free Guy? That’s the only movie that I have that I exhibited the problem for me. Movies that others complained about like Aladdin never glitched for me. But Free Guy?! Yea that one was really bad. Yesterday when I tested Free Guy it played with no issues so it would be interesting to see how it works for others.

Thanks for doing that. It’s an easy one to test at the aforementioned time stamp. 50:49, right as stuff clatters onto the floor.

As soon as I get it, I’ll rip it with MakeMKV and report my results.

I’ve got this on my to-watch list, do you remember if there’s a timestamp to look out for in Free Guy?

So just watched Free Guy 4K w/Atmos, I noticed it dropped out once around the 1:22:29 mark.

When I first had the problem with Free Guy, it was not just a few spots in the movie. It was every few minutes. Very noticeable.

I’ll try this on my setup.

Just checked 1:22:29 (started at 1:19:xx and now at 1:25:xx) and I had no audio glitch. Did you rip Free Guy yourself, or get it elsewhere. If you ripped it, did you do it using MakeMKV? And did you do any other processing (like Handbrake, etc?) I ripped my copy myself using MakeMKV and did no further processing. In MakeMVK it do have it strip out all non-english audio and subs.

Just tested Free Guy and had the momentary sound glitch at 1:22:29, too.

This was a copy I’ve sourced, was made using MakeMKV from what I can see via MediaInfo.

Here’s a Free Guy extract if you care to test?

Very interesting, I’m in the process of ripping Toy Story 2, and this intrigues me (from the MakeMKV log):

Oh wow. So it’s in the source?

I’d say more that it may be a bug in MakeMKV. Some time ago the developer made a lot of changes to improve Atmos. It may be that he hasn’t quite fix all the problems yet.

I haven’t actually watched TS2 yet to test it. I do see these sync issues all the time when ripping and they never cause any audio glitches for me. Maybe some AVRs are just more sensitive to it.

Yes I’ve seen these errors all the time when ripping movies. But…why is it an issue this particular time?

I can’t answer that. But give me about an hour and I’ll actually test watching TS2 and report if I hear the glitch or not. If I do hear it, maybe it give use something to go to the MakeMKV developer with.

Ok, so I checked TS2 at 50:49 when the purse falls to the floor. And I hear no audio glitch at all.

@WilliamG what version of MakeMKV did you use to rip TS2? I used the latest version (1.16.7). If you ripped TS2 with an older version, maybe try again with the latest? It could be that you ripped your copy before he fixed the Atmos bug.

It was a while ago, when it came out. I’ll grab my disc, re-rip, and report back. Cheers!

The main fix was in 1.15.4 released in December 2020
(as from my post in November 2021):

IMO, every TrueHD disc ripped with < 1.15.4 should be re-ripped!

That would take me longer than I can even think to do. Thankfully it’s just my Disney movies, but I’ve also got quite a few of them…
