python – PyAudio输入溢出-9981 – 没有解决方案正常工作

所以,
我试图在我的RaspberryPi模型B板上运行PyAudio示例录制程序,
这是我得到的错误,

Traceback (most recent call last):
  File "/home/pi/pyaudio/test/testing.py",line 23,in <module>
    data = stream.read(chunk)
  File "/usr/local/lib/python2.7/dist-packages/pyaudio.py",line 605,in read
    return pa.read_stream(self._stream,num_frames)
IOError: [Errno Input overflowed] -9981

有一些解决方案可以解决许多用户的问题,在我看来,这是不正确的.

这是我试过的,

首先,这是代码,

"""PyAudio example: Record a few seconds of audio and save to a WAVE file."""

import pyaudio
import wave

CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.wav"

p = pyaudio.PyAudio()

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

print("* recording")

frames = []

for i in range(0,int(RATE / CHUNK * RECORD_SECONDS)):
   data = stream.read(CHUNK)
   frames.append(data)

print("* done recording")

stream.stop_stream()
stream.close()
p.terminate()

wf = wave.open(WAVE_OUTPUT_FILENAME,'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()

如果支持或不支持当前配置,我也尝试过,

import pyaudio
p = pyaudio.PyAudio()
if p.is_format_supported(48000.0,input_device=1,input_channels=1,input_format=pyaudio.paInt16):
    print 'True!'

44,000和44,100都是支持,但我仍然一次又一次地得到同样的错误.

这是我的USB音频卡设备信息,

p.get_device_info_by_index(1)

{'defaultSampleRate': 44100.0,'defaultLowOutputLatency': 0.011609977324263039,'defaultLowInputLatency': 0.011609977324263039,'maxInputChannels': 1L,'structVersion': 2L,'hostApi': 0L,'index': 1,'defaultHighOutputLatency': 0.046439909297052155,'maxOutputChannels': 2L,'name': u'Generic USB Audio Device: USB Audio (hw:1,0)','defaultHighInputLatency': 0.046439909297052155}

有没有人知道为什么我仍然会收到错误？
