How does abuse open the music files?

[AspenNorwood]

I'm having some trouble getting the music to play in Linux. I had a build of 0.8 where the music was working but it's stopped working and I don't know what I did and I've never managed to get it playing in 0.9 yet.

I was wondering if you could explain how the game is opening the hmi files so I can figure out what's going wrong? For example, does SDL mixer open them directly or pass them on to another program? I'm not knowledgeable enough to just read the code and figure it out.
