java Fmod and GAGE

I’m currently working on a simple 2d game clone of an old C64 game. As low-res timer I use GAGE. What i relly want is good quality sound and I want to use a remix of the old original use the gunes in mp3 format. If I GAGA sound API with the render method in my main loo everything runs smooth. But since I found no way using GAGE sound playing neither mp3 files or to play sounds in loop mod I’ve considered using “Jouvieje’s” java wrapper to FMod. BUT my implementation of streaming a mp3 file slows down my game by far, making it unplayable. Has anyone any clue on how to make the two API’s work together. All FMod initialization is made prior to the game’s main loop, and I dubt the game rendering i written in such poor fashoin that there will be no more CPU left to play the sound. If anyone could give me a small snippet of code to give me a hint ?, or if nesseseary I could post a pseudo/example of my implementation. I use GAGE to render at a fixed 60 FPS rate.
