I’m on an Apple TV 4k on TVOS 14.5, Infuse Pro 6.6.4 (3552), with an LG 65C9 over eARC into a Pioneer VSX-LX503 receiver. I’ve noticed that some Dolby Digital Plus Atmos samples aren’t working with Infuse on the ATV4k, for instance some of the samples here: https://thedigitaltheater.com/dolby-trail…

This happens with the Dolby demos. Post the media info. I found if the track contains both TrueHD and eac3 atmos it doesn’t work. The same problem occurs on my nvidia shield TV which supports pass through. Dolby buggered up the encodes.

Thanks for this info, had no idea, was bewildered as to why some of my trailers with multiple audio tracks didn’t play in atmos. [image]

Edited the tracks to have the one atmos E-AC-3 track, doesn’t work, still triggering just LPCM, anything to do with the 7.1 set up? Maybe only works with 5.1 E-AC-3? [image]

I have webrips with 7.1 atmos that work. It’s the trailers. Something is botched in the encode. They didn’t play right with nvidia shield tv either.

Do you have a sample you can share? The trailers play fine on my AVR when bitstreaming through Windows.

Ok the reason is because atmos tracks need to have a delay no more than 500 ms apart, so if there’s truehd 7.1 atmos and eac3, it can cause issues, easy solution is mkvtoolnix, what ever delay is on eac3 file e.g 1000ms, or 1 sec, then what you do is create separate truehd track and add a -1000ms, t…

This issue was addressed here. It’s an issue with the AppleTV itself and the way atmos was implemented in these files. I’m assuming nvidia handles it the same way.
