标签: python linux alsa portaudio

我有几个月前编写过的Python脚本(当时工作正常,所以我的问题不是代码相关的),但它并不适用于我需要的系统上周成立。 我为所有调用音频的Python脚本收到以下错误(我猜它与Python无关):

portaudio error in Pa_OpenStream: Invalid number of channels

Portaudio error: Invalid number of channelsportaudio error in 
Pa_AbortStream: Invalid stream pointer

portaudio error in Pa_CloseStream: Invalid stream pointer
