when i try to run kingdom hearts, the graphic run at a very nice 40 fps with little skips every once in a while, but still very playable, the sound however can either stutter like hell, or i can enable time stretching which makes it go in slow-motion. i cant live with the sound in slow-motion, but i dont really wanna play with the stutters. Im useing the ZeroSPU2 sound plugin
Your game isnt running at full speed which is why it stutters, so either you live with the stuttering, the slowmotion or turn it off all together.

Show us your PC specs and PCSX2 settings then maybe we can help a bit for that speed, for the stutter problem you should try using the SPU2-X or P.E.Op.S plugins.
