title: pyaudio-OSError: [Errno -9999] Unanticipated host error
body: <p>I just want to run a simple python audio code:</p>
  
  <pre><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)
  </code></pre>
  
  <p>but I got the following error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "rec2.py", line 17, in &lt;module&gt;
      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
  </code></pre>
  
  <p>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.</p>
  
  <p>what is the problem?</p>
