使用 python 2.7 运行以下代码时(在 Ubuntu 14.04 中)
import pyaudio
p = pyaudio.PyAudio()
我收到以下异常:
ALSA lib pcm_dsnoop.c:618:(snd_pcm_dsnoop_open) unable to open slave

非常感谢您的帮助
最佳答案
您是否安装了 bluez-alsa 软件包？如果是这样，请将其删除并重新测试。应该消除错误。
如果没有，这里也有一些讨论(https://github.com/Katee/quietnet/issues/18)可能会有所帮助。
ALSA lib pcm.c:7843:(snd_pcm_recover) underrun occurred
The underun is likely caused because pulseaudio is already accessing
the card - you can pause it using http://linux.die.net/man/1
/pasuspender. In general to avoid such deadlock, you need a
soundserver like jackd https://help.ubuntu.com/community/What%20is%20JACK, but you already figured this out from the following log
entries in your trace ;-) (apt-get install jackd)
