Codec ID: A_PCM/INT/LIT instead A_MS/ACM

Please use the Codec ID: A_PCM/INT/LIT when create mkv tracks from PCM bluray tracks, instead A_MS/ACM.
Many demuxers work fine with A_MS/ACM but MkvExtract reject that Codec ID to extract WAV/W64 files, and I think the reference must be the MkvToolNix tools.
More info and sample.

I was curious about this, so I searched through all of my rips. Some of them do have the Codec ID: A_PCM/INT/LIT, but others have the A_MS/ACM.
All the rips I have with the Codec ID: A_PCM/INT/LIT all seem to be for audio tracks that are either mono or stereo. The multichannel tracks have the other codec ID.

You are right, with mono or stereo files we don't need know the ChannelMask of the PCM data, with multichannel we need the A_MS/ACM Codec Private data to store that info.
Maybe the correct behaviour is remain using A_MS/ACM and improve other soft begining by mkvmerge and mkvextract.
I write to MKVToolNix developper about this:
