 Yes, it's the issue with the file. QDM2 audio in files generated by
 mkvtoolnix-6.6.0 are broken (this bug was fixed in mkvtoolnix-6.7.0). You
 don't have to fix FFMPEG for them.

 > and if i understood correctly the spec did not list A_QUICKTIME either.

 Please look at http://matroska.org/technical/specs/codecid/index.html.
 A_QUICKTIME/**** Codec ID is deprecated in favor of A_QUICKTIME (without a
 trailing codec name).

 VLC does not support neither Matroska A_QUICKTIME nor A_QUICKTIME/****
 Codec IDs at all. I've opened https://trac.videolan.org/vlc/ticket/11038
 for this issue.

 > please lets move qdm2 to a seperate ticket

 OK, I'll open new ticket for using A_QUICKTIME instead of deprecated
 A_QUICKTIME/**** Codec IDs, when
 https://trac.videolan.org/vlc/ticket/11038 is closed.
