Ios 使用AudioQueue播放原始未压缩声音，无声音

我使用三个缓冲区和一个队列，通过网络播放ADPCM数据。数据从我的应用程序中解码，解码后的数据未压缩的pcm数据通过Audacity播放正确验证。但是，当使用AudioQueue从我的应用程序播放时，我听不到任何声音。所有AudioQueue API返回值均为noErr 0。我一直在尝试分配三个缓冲区。这对我没用！有人知道如何显示更多的AudioQueue日志，这样我就可以抓住故障点，或者我的代码中是否存在任何问题？谢谢

结果我没有设置mBytesPerPacket和mBytesPerFrame。结果我没有设置mBytesPerPacket和mBytesPerFrame。
