Need help with .mkv dual audio files.

[Eternal.]

I have downloaded 1080p .mkv files that are dual audio. I have had no luck of getting them to play in english though. They play in japanese with subtitles, but isn't dual audio supposed to be dual? lol

I am using the Kmplayer, but I am willing to use other video players I suppose. Thank you for your help!
