未处理的异常，没有可用的源代码

我试图让我的音轨使用FMOD播放，但我一直得到一个未处理的异常，然后它说没有可用的源代码，并向我展示反汇编代码。

main.cpp
        bool AudioProject::initAudio()
    {
        // Audio code
        fmSound = new Sound();
        fmSound->initialise();
        fmSound->load("Music/Rocky_Theme_Tune.mp3");
        fmSound->play();
        return true;
    }

我把断点放在它停止的地方，这是在initialize函数中。它甚至进入了initialize函数，然后随机中断。我想我有每一个包含文件的fmod，因为我去年使用它没有问题。

我也会贴出我的sound.h/.cpp文件。

遇到了瓶颈，有人有什么想法吗?
