意思是服务器报异常：因为关闭了终端SSH，而代码中有 print()，导致没有位置可输出打印，导致报错 服务器是计算机的一种，它比普通计算机运行更快、负载更高、价格更贵。服务器在网络中为其它客户机（如PC机、智能手机、ATM等终端甚至是火车系统等大型设备）提供计算或者应用服务。服务器具有高速的CPU运算能力、长时间的可靠运行、强大的I/O外部数据吞吐能力以及更...

snd_pcm_hw_params_set_rate_near () 函数设置音频数据的最接近目标的采样率。snd_pcm_hw_params( ) 从设备配置空间选择一个配置,让函数 snd_pcm_prepare() 准备好 PCM 设备,以便写入 PCM 数据。snd_pcm_writei() 用来把交错的音频数据写入到音频设备。
