Comment:
"aac 6 channels" Your little file has Cb channel in place of LFE. That
channel is Back Centre. We do support this, but AC3 does not, so it needs
convertion and '''we do not support that'''.
See this for clarity, last MediaInfo Name says that Cb means back center
that is right behind your head perfectly.

Older version just creates L R C Ls Rs file, i.e. 5.0 file.
