以下腳本輸出以下內容并顯示我遇到的問題：
#!/usr/bin/env python
import pyaudio
from pprint import pprint
p = pyaudio.PyAudio()
# SUCCEEDS
pprint(p.is_format_supported(input_format=pyaudio.paInt8,input_channels=1,rate=44100,input_device=0)) # => True
try:
stream = p.open(format=pyaudio.paInt8,channels=1,rate=44100,input=True,frames_per_buffer=1024)
data = stream.read(1024)
except IOError as e:
print 'This never happens: '+str(e)
# FAILS
pprint(p.is_format_supported(input_format=pyaudio.paInt8,input_channels=1,rate=22050,input_device=0)) # => True
try:
stream = p.open(format=pyaudio.paInt8,channels=1,rate=22050,input=True,frames_per_buffer=1024)
data = stream.read(1024)
except IOError as e:
print 'This fails: '+str(e)
# FAILS
pprint(p.is_format_supported(input_format=pyaudio.paInt8,input_channels=1,rate=22050,input_device=0)) # => True
try:
stream = p.open(format=pyaudio.paInt8,channels=1,rate=22050,input=True,frames_per_buffer=512)
data = stream.read(1024)
except IOError as e:
print 'This also fails: '+str(e)
# FAILS
pprint(p.is_format_supported(input_format=pyaudio.paInt8,input_channels=1,rate=11025,input_device=0)) # => True
try:
stream = p.open(format=pyaudio.paInt8,channels=1,rate=11025,input=True,frames_per_buffer=512)
data = stream.read(1024)
except IOError as e:
print 'This also fails as well: '+str(e)
stream.stop_stream()
stream.close()
p.terminate()
以上輸出如下：
True
True
This fails: [Errno Input overflowed] -9981
True
This also fails: [Errno Input overflowed] -9981
True
This also fails as well: [Errno Input overflowed] -9981

如果要檢查作業系統和硬體是否支持所需的格式,通道,速率等設定,請執行以下操作：import pyaudio
soundObj = pyaudio.PyAudio()
# Learn what your OS+Hardware can do
defaultCapability = soundObj.get_default_host_api_info()
print defaultCapability
# See if you can make it do what you want
isSupported = soundObj.is_format_supported(input_format=pyaudio.paInt8, input_channels=1, rate=22050, input_device=0)
print isSupported
isSupported將為True,因為您的系統可以處理您的設定.記憶體溢位錯誤可能是由于某些作業系統硬體問題引起的.您必須檢查您的默認主機API實際可以執行的操作.您不需要通過“流類”“打開”和“關閉”soundObj來查詢它.
看看這個問題：PyAudio Input overflowed

事實證明,“Errno輸入溢位–9981”并不是一個小問題：http://trac.macports.org/ticket/39150
我看到你有最新的portaudio版本(19.20111121),但19.20111121_4聲稱修復了這個bug.看看升級portaudio是否有效.
