我在 Python 2.6.6 下运行 PyAudio，希望它使用 ALSA 而不是 JACK。
In [1]: import pyaudio
In [2]: pa = pyaudio.pa
In [3]: pa.initialize()
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started
最佳答案
对于那些碰巧通过 Google 发现自己遇到这个老问题的人:
pyaudio显示的信息...
jack server is not running or cannot be started
...提供信息，而不是错误。这意味着 portaudio 尝试连接到 Jack 但失败了，但并不意味着它放弃了一切。
此时，您应该拥有一个使用 ALSA 的功能齐全的 PyAudio 对象。您可以通过例如查看可用设备列表来验证这一点:
>>> import pyaudio
>>> pa = pyaudio.PyAudio()
[...lots of crap from ALSA...]
Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started
>>> print '\n'.join([y['name']
... for y in [pa.get_device_info_by_index(x)
... for x in range(pa.get_device_count())]])
bcm2835 ALSA: - (hw:0,0)
bcm2835 ALSA: IEC958/HDMI (hw:0,1)
USB Audio Device: - (hw:2,0)
