Well there,s a lot of links to follow but if you know how to film and enable raw modules you should be able to do the same to mlv.
I would suggest to follow this link and start reading
http://www.magiclantern.fm/forum/index.php?topic=7122.msg96859#msg96859
The first page of the link has the sound module and the mlv module needed to record audio (a wav file) which you have to synch in post.
Good luck
