Doing a Remux, mkvtoolnix exit code 2

[maudit]

Hi, I need some help please,
I'm using mkvtoolnix and I'm dealing with adding a dub PCM audio from another source,
and I get the following error message, can I fix it?

The file PCM was not recognized as a supported format (exit code 2).


checking both PCM files with mediainfo,
the first already encapsulated is this:

_ - 3 - PCM, English, 2.0 channels, 24 bits, 48kHz.pcm
Format                      : MPEG Audio
File size                   : 1.44 GiB
Overall bit rate mode       : Variable
FileExtension_Invalid       : m1a mpa mpa1 mp1 m2a mpa2 mp2 mp3

Audio
Format                      : MPEG Audio
Format version              : Version 1
Format profile              : Layer 3
Format settings             : Intensity Stereo + MS Stereo / CCITT
Bit rate mode               : Variable
Channel(s)                  : 1 channel
Sampling rate               : 48.0 kHz
Compression mode            : Lossy
Stream size                 : 1.44 GiB (100%)

while the PCM that does not load is this, with missing info:

 - 3 - PCM, Italian, 2.0 channels, 16 bits, 48kHz.pcm
File size                   : 980 MiB

while using useac3to to create a FLAC from the PCM, I had no problems at all.

Convert to WAV.

Convert to WAV.

I never did it before, I don't even know how to do it.
anyway I can't cause I have to use one of the original untouched tracks,
one is PCM, that I would like to use, the other is the DTS-MA that instead, works without errors.

Have you used software to decrypt protected Blu-ray? Because mkvmerge only supports unencrypted media, so your files are perhaps encrypted or just corrupted.

I don't know if it's corrupted, eacto does not say anything..
..anyway, they now just told me I can use FLAC instead of PCM, so I'm fine..
problem solved,, nevermind.. sorry.
