I always back up my Blu-ray discs. First I copy them with MakeMKV and then I compress the resultant MKV file(s) with HandBrake. When using a Debian-based OS, I have no trouble with LPCM audio files which HandBrake converts to AC3. But, when using GeckoLinux (a fork of openSUSE Tumbleweed), MakeMKV copies the Blu-ray disc perfectly and the LPCM track is present (AND the computer plays the track!). However, when I open that MKV file with HandBrake in order to compress it, the LPCM audio is not even shown!
I own two new and different computers (an Alienware gaming computer [i7 Skylake] and an Asus gaming computer [i7 Kabylake], both with Windows completely wiped off) on which I'm running GeckoLinux as the only operating system and the problem occurs on both.
Tell us about your environment. What version of HandBrake? What version of Linux / Unix are you running. etc.
I am using the latest (v.1.0.7) HandBrake which is updated frequently from the Packman repositories. I am running GeckoLinux, a fork of openSUSE Tumbleweed. I update the two computers at least once every day. These computers are the ones on which the problem occurs.
I also own two other computers which both run MX Linux; these also have i7 processors but they are not as fast as the ones on the computers running GeckoLinux. I also update the systems every day. On those two HandBrake does indeed recognize the LPCM track(s) contained on the MKV file(s) and converts them to AC3 perfectly. (The computers both use the HandBrake nightly build.)
If there was any exception or error displayed, please copy it and paste it here:
No error is shown. It's as though the LPCM track never existed.
Please include the scan or encode log:
There is none.

Paste a log of the scan or encode between these code brackets, or use a pastebin website and provide us with the URL it gives you. Logs are required for all support requests.
I do not understand why this is occurring. The problem does not occur, as I mentioned, with a Debian-based OS (on the two computers on which I am currently using MX Linux). So I am forced to compress such MKV files on one of those computers.
But my two newer computers, running GeckoLinux, are much faster and I use one or both for all Blu-rays which do NOT have an LPCM track but I would surely like to be able to use those computers for ALL Blu-rays.
It's not as though I cannot back up Blu-rays with LPCM tracks - I can by using the slower computers - but I cannot understand why this problem occurs (can anyone duplicate it?) and I hope that it can be explained and fixed.
Can anyone offer some help?
