FF9 Sound Problem

[LegendHero]

Well, whenever I go into battle, there is a sound problem. It is hard to explain but the best I can explain it is that the sound "doubles" so to speak. Like in the middle of the battle, one part of the sound will just freeze and keep playing, most of the time even after the battle is finished, the sound is still "frozen" while I'm still walking around. This also happens with the victory music, but that ends after I exit the battle screen.

Any suggestions?

I'm running 1.5.2 btw
