Blender sound stops working

Hi guys, how are you?
I need some help please. I´m making a shmup game, and when there are too much sounds playing at the same time (For example bullet sound + explosions + song) the song stops playing (Even if it is in Loop End + true triggering)
I don´t know what to do…
I´m finishing this project in blender 2.49b.
Any help would be appreciated
Thanks for your time!
