pyaudio-OSError: [Errno -9999] 意外的主机错误

Question

I just want to run a simple python audio code:

import pyaudio
import wave
import sys

CHUNK = 1024
wf = wave.open("4.wav", 'rb')
# instantiate PyAudio (1)
p = pyaudio.PyAudio()
# open stream (2)
stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
                channels=wf.getnchannels(),
                rate=wf.getframerate(),
                output=True)

but I got the following error:

Traceback (most recent call last):
  File "rec2.py", line 17, in <module>
    output=True)
  File "C:\Users\Surena\Anaconda3\lib\site-packages\pyaudio.py", line 750,  in open
    stream = Stream(self, *args, **kwargs)
  File "C:\Users\Surena\Anaconda3\lib\site-packages\pyaudio.py", line 441, in __init__
    self._stream = pa.open(**arguments)
OSError: [Errno -9999] Unanticipated host error

I tried another pyaudio record too, the same error came up. I also tried uninstall pyaudio and install it again using pip install pyaudio, but it did not help. I even uninstalled anaconda3 and reinstall it.nothing changed.

what is the problem?

Answer 1

我遇到了同样的问题，我只是通过在“设置”>“机密性”>“麦克风”（在 Windows 10 上）中启用/禁用对麦克风的访问来解决它

Answer 2

You need to collect additional information to understand the problem. From Portaudio docs :

PortAudio usually tries to translate error conditions into portable PaError error codes. However if an unexpected error is encountered the paUnanticipatedHostError code may be returned. In this case a further mechanism is provided to query for Host API-specific error information. If PortAudio returns paUnanticipatedHostError you can call Pa_GetLastHostErrorInfo() to retrieve a pointer to a PaHostErrorInfo structure that provides more information, including the Host API that encountered the error, a native API error code and error text.

If you have this error on Linux, most likely it is caused by incompatible sample rate you are trying to request from the driver. This value

            rate=wf.getframerate()

can be changed to 16000, 44100 and 48000 to test which rate is actually supported.

Answer 3

我遇到了同样的问题，所以我只是从设置中授予麦克风权限，其工作只需转到设置 --> 隐私 --> 麦克风，然后在麦克风上授予麦克风权限

Answer 4

如果您使用的是 Windows 10 搜索麦克风隐私设置

Answer 5

Okay so if you using jupyter-notebook and you face this challenge. install pyaudio with homebrew(brew install pyaudio) and then restart your kernel.
