I've tried to do a straight conversion of this file to mkv using latest
git tree of mkvtoolinx. It seems to work fine except for one thing.
It seems it confuse sampling freq and channels count. Here is what
mkvinfo show for the truehd track:
+ Audio track
+ Sampling frequency: 6.000000
+ Channels: 48000
This only happens for truehd (and maybe mlp, I haven't tried).
