Python中的音频文件无法播放

如何解决Python中的音频文件无法播放

我尝试在python中播放音频文件，但是几秒钟后，出现以下问题：

Expression 'ret' Failed in 'src/hostapi/alsa/pa_linux_alsa.c',line: 1736
Expression 'AlsaOpen( &alsaApi->baseHostApiRep,params,streamDir,&self->pcm )' Failed in 'src/hostapi/alsa/pa_linux_alsa.c',line: 1904
Expression 'PaAlsaStreamComponent_Initialize( &self->playback,alsaApi,outParams,StreamDirection_Out,NULL != callback )' Failed in 'src/hostapi/alsa/pa_linux_alsa.c',line: 2175
Expression 'PaAlsaStream_Initialize( stream,alsaHostApi,inputParameters,outputParameters,sampleRate,framesPerBuffer,callback,streamFlags,userData )' Failed in 'src/hostapi/alsa/pa_linux_alsa.c',line: 2840

我正在使用“导入wave”打开音频文件。
