Cricket Audio stops working for no apparent reason

Hello, I’m writing this text using google translator, please forgive any language problem.

I have a problem with Cricket Audio, it works fine for a while during the game, but at some point it just stops playing, it happens when I change from one level to another when I change the scene.
Could you tell what might be happening?

I’ll send a part of the code:

SoundEngine.cpp:

SoundEngine * SoundEngine::_mySingleton = NULL;

SoundEngine * SoundEngine::getInstance()
{
    if(_mySingleton == NULL)
    {
        _mySingleton = new SoundEngine();
        Director::getInstance()->getScheduler()->scheduleUpdate(_mySingleton, 10, false);
    }
    return _mySingleton;
}

void SoundEngine::update(float delta)
{
    CkUpdate();
}

SoundEngine::SoundEngine()
{
#if CK_PLATFORM_ANDROID
    // O config e inicializacao estao no AppActivity.java
    // e tem JNI lá no SonarCocosHelper
#else
    CkConfig config;
    CkInit(&config);
#endif

    _BANK_EFEITOS = CkBank::newBank("res/Som/Som-Efeitos.ckb");

    _SOM_GRAMA = CkSound::newBankSound(_BANK_EFEITOS, "1");
    _SOM_ESTRELA = CkSound::newBankSound(_BANK_EFEITOS, "2");
    _SOM_CAINDO = CkSound::newBankSound(_BANK_EFEITOS, "3");
    _SOM_GRITANDO = CkSound::newBankSound(_BANK_EFEITOS, "4");
    _SOM_HEIM = CkSound::newBankSound(_BANK_EFEITOS, "5");;
    _SOM_LAVA = CkSound::newBankSound(_BANK_EFEITOS, "6");
    _SOM_AREIA = CkSound::newBankSound(_BANK_EFEITOS, "7");
}

In others classes:

SoundEngine::getInstance()->_SOM_GRITANDO->play();
or
SoundEngine::getInstance()->_SOM_GRAMA->play();
or
SoundEngine::getInstance()->_SOM_ESTRELA->play();

I think you should write to cricket engine support team.

I have written a few days, but there was no answer, so I wrote here hoping someone would help.

Here probably only 1 or 2 peoples was using circket - but not much info about it. So best is to write to them they ussualy reply - could be some delay.
