PyAudio: how to capture internal audio (not from microphone)?

问题

Tried like this:

p = pyaudio.PyAudio()

stream = p.open(format=FORMAT,
            channels=CHANNELS,
            rate=RATE,
            output=True,
            frames_per_buffer=chunk)

all = []
for i in range(0, int(RATE / chunk * RECORD_SECONDS)):
    data = stream.read(chunk)

but it throws paCanNotReadFromAnOutputOnlyStream
Using input=True it reads audio from mic, but that is not what I need.
Any help, please
Edit: I am using linux
I can also use other library, not only PyAudio. I just need to get this work

Try this: https://github.com/intxcc/pyaudio_portaudio

PyAudio isn't made to record outputs, only inputs. This fork however introduces an api that gives you the ability to do so through loopback mode. To use this, set the flag as AUDCLNT_STREAMFLAGS_LOOPBACK. Hopefully this works and good luck!
