                How to remove an audio track from an mkv
              
          
        
      
        
  
      
    
Install mkvtoolsnix.
brew install --with-qt5 mkvtoolnix
Use mkvinfo to get the audio track IDs that you want.
mkvinfo *.mkv
Note that the audio track IDs are not the track numbers. Check the man page of mkvmerge or mkvinfo for more details.
Use mkvmerge to create a copy of the mkv with ONLY the desired tracks using --audio-tracks.
mkvmerge -o out.mkv -a 2 orig.mkv
