Audio does not play .mkv files on iPad/iPhone any more - used to - Video fine

[memoryless]

I had a file that had two sound tracks on it - spanish and english. The player on the stick does not know how to hand it and the audio was muted. It was MKV too I believe. You’ll need to re encode the movie with just the one sound track - USE VLC media player. If you’re not tech savy then this is way too complicated for the average user I’m using it on an iphone.
