未知的PCM cards.pcm.rear(pyaudio)

Question

这个问题与这个pydub-Issue有关.他们告诉我错误信息与pyaudio有关.

#!/usr/bin/env python3

import pydub, pydub.playback

wav = pydub.AudioSegment.from_wav('/home/user/complete.wav')
pydub.playback.play(wav)

这段代码引发了我不理解的错误.

ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe

Cannot connect to server socket err = No such file or directory

wav本身发挥得很好.我该如何防止这些错误.

Answer 1

删除以下蓝牙套件时删除拒绝的连接(如果你真的想) sudo apt-get remove bluez-alsa

通过注释掉相关的行来删除未知的PCM卡/usr/share/alsa/alsa.conf.

其他我不知道的,但你可以开始看这里:PyAudio工作,但每次吐出错误信息.
