After months of working, I learned the most important lesson on Cocos2D. The retain increase by one when you put any CCNode object on a CCArray or NSArray or NSDictionary... This means you must release the objects from this objects before the CCLayer or CCScene dealloc.

You must put a [array removeAllObjects] or [dictionary release] on the - (void) cleanup and after all your objects has removed, then put a [super cleanup];

In the meantime, on - (void) onExit you must remove all scheduler from the instance. Not only a scheduler itself. Remember to stopAllActions on any CCNode. But, carefully, because stoping actions from CCNodes (Sprites or something) must be on cleanup, before any removeAllObjects.

And remember: if CCLayer or CCScene does not remove properly, SimpleAudioEngine not will release the audio too.
