I just purchased the "4k" version of "The Fifth Element". This is a standard BD, just with higher quality video and atmos audio. Unfortunately, the English TrueHD audio channel is missing -- I see TrueHD in French (which the back of case lists as NON atmos) but only regular DD 5.1 in English.

I'm running MakeMKV 1.10.4 on Ubuntu Linux 14.04 LTS.

There was a message earlier that the Atmos track was only available on the 4K version, which MakeMKV can't read at this time.

Thanks for the suggestion, but this is a regular BD with dolby atmos audio. It's "Mastered in 4k", not an actual 4k UHD disk.

Here's more info on the disk:

Thanks for any tips. Is there any additional info I can provide to help debug?

I see the same issue with "Star Trek Beyond". The Bluray lists Dolby Atmos, but I'm only seeing a "DD 5.1" option to rip. When I play the resulting MKV, my Denon receiver confirms that it is regular Dolby 5.1. Playing the bluray directly with the same receiver shows atmos audio.

This is with MakeMKV v1.10.4

I found a windows 10 machine and installed v1.10.4 win(x64-release). This successfully found the TrueHD / atmos audio track, which I confirmed via playback on my Denon receiver.

So it seems the missing atmos issue is only Linux, not windows.
