I have Nplayer installed on my iPad and iPhone.
https://itunes.apple.com/au/app/npla...539397400?mt=8
It works great except for some .mkv files
It displays audio codec not available.

I am hoping someone else also has this problem but knows how to fix it.
Is it just a case of applying a different Mezzmo profile to my iPad?
The profile is currently set to Generic PAL
