PyAudio Input Overflowed -9981 – 没有解决方案工作

PyAudio Input Overflowed -9981 - No solution working

请不要将此问题报告为重复问题，因为没有任何可用的解决方案适合我，我对它们都进行了测试

所以，

我正在尝试在我的 RaspberryPi 模型 B 板上运行 PyAudio 示例录音程序，

这是我得到的错误，

num_frames a€"要读取的帧数。

exception_on_overflow a€" 指定是否应在输入缓冲区溢出时抛出(或静默忽略)IOError 异常。默认为真。

引发 IOError：
