python-pyaudio：OSError：[Errno输入溢出] -9981

Question

我正在使用树莓派来录制音频：按按钮开始录制，再按一次按钮停止录制。但得到错误：

Traceback (most recent call last):
  File "/home/pi/november03 fullscreenwithoutdots.py", line 225, in <module>
    record_audio(is_recording, button_pressed)
   File "/home/pi/november03 fullscreenwithoutdots.py", line 154, in record_audio
    data = stream.read(CHUNK)
   File "/usr/lib/python3/dist-packages/pyaudio.py", line 605, in read
    return pa.read_stream(self._stream, num_frames)
OSError: [Errno Input overflowed] -9981

我搜索了在线解决方案，但在我的情况下它们都没有效果，我从官方文档中成功运行了示例。谁能帮我？非常感谢你。以下是我的代码：

recording_started = False
CHUNK = 8192
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
    )

frames = []

def record_audio(is_recording, button_pressed):
    CHUNK = 8192
    FORMAT = pyaudio.paInt16
    CHANNELS = 1

    WAVE_OUTPUT_FILENAME = "output.wav"

                break

                data = stream.read(CHUNK)
                frames.append(data)
                print('recorded')

        timer = MyTimer(stopFlag,time.clock())
        #timer.start()

        screen.blit(background, (0,0))

        stopFlag.set()

        record_audio(is_recording, button_pressed)

    else:

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

        print('stop outside')
        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()
