No Audio on a MKV file

First of all i’d like to say hallo to all the forum.

I am not too sure about the codecs, but sometimes I have mkv files that have no sound as well.  I have found out that if you press the mute button twice the sound will work.  I have no idea why this is but that fixes it for me.
