Lots of problems with Project M 3.6

[martzfartz]

I recently installed project m 3.6 using this tutorial, and there are a few problems. A lot of the music is staticy, crackly, and loud. Some just isn't the correct music (e.g. fountain of dreams is a distorted mario kart song). Character portraits for player 2 are just blank grey. If you try to save a snapshot from the pause screen it's just static. Replays are messed up where the characters will just get in an endless loop of turning back and forth. Any help?
