preloadEffect Memory Leak

Hi all I have searched in the forum for this issue but with no luck.

So I’m a newbie in cocos2d and start using sounds effects and so, I’m using SimpleAudioEngine::sharedEngine()->preloadEffect(“sound.mp3”) , and all is alright , but when I use Xcode Instruments I’m getting a memory leak. Then I have compiled the space game example that has some sounds effects, and Instruments give me an other memory leak at the preload lines.

Then I have updated my cocos2dx version to cocos2d-2.1beta3-x-2.1.0 with the same result.

Can somebody help me with this issue?

Thank you in advance.

Is this usual or I’m doing something wrong???, I have follow the tutorials and all the examples have leaks…
Please give me some orientation … :stuck_out_tongue:
