我正在开发一个原生的android项目，并尝试使用OpenSL来播放一些音频效果。使用VisualGDB提供的本地音频样例项目，我编写了下面的代码。OpenSL：通过AAsset_read加载wav文件时导致静态的是什么？
接近尾声时，您可以看到我注释了一行，它将缓存中名为hello的变量的内容存储到目标中。你好来自示例项目，并包含大约700行字符像这样：
“\ x02 \ x00 \ x01 \ x00 \ xff \ xff \ x09 \ x00 \ x0c \ x00 \ x10 \ x00 \ x07 \ x00 \ x07 \ x00“
其中有人说”你好“的音频文件。当将该字节数据读入流中时，我的代码工作正常，并且在运行应用程序时听到“hello”。然而，当我从wav文件读取播放我想要的资产时，我只听到静止的声音。数据缓冲区的大小与文件的大小相同，因此它看起来正在被正确读取。静态播放的wav文件（或非常接近它）的持续时间。
我对数据格式或音频编程一无所知。我试着用不同的枚举值调整一些format_pcm变量，但没有成功。使用我在Internet上找到的名为GSpot的工具，我知道以下关于我试图播放的音频文件：
文件大小：557 KB（570,503字节）（与数据缓冲区的大小相同 AAsset_read返回
编解码器：PCM音频
采样率：48000Hz
比特率：1152 kb/s的
通道：1
任何帮助或方向将不胜感激。
