Python - use rate in pyaudio/format/any other value error are given in the chunk: [Errno Input overf

Operating system: Mac OSX 10.7.5 Python: Python 2.7.3 (homemade software) pyaudio: 0.2.7 portaudio: 19.20111121 (homemade - portaudio)
The following script output problems and show me the following content:

#! The/usr/bin/env python
The import pyaudio
The from pprint import pprint

P=pyaudio. Pyaudio ()

Stream. Stop_stream ()
Stream. The close ()
P.t erminate ()

The above output is as follows:

True
True
This fails: [Errno Input overflowed] - 9981
True
This braking fails: [Errno Input overflowed] - 9981
True
This braking fails as well: [Errno Input overflowed] - 9981

If you want to check whether the operating system and hardware to support the required format, channels, rate Settings, do the following:

The 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 will is True, because your system can handle your Settings. Out of memory error may be caused by certain operating system hardware problems. You must check your default host API can actually do. You don't need to "stream class" "open" and "closed" soundObj to query it.
Look at this question: PyAudio Input overflowed

Editor:
Facts have proven that "Errno input overflow - 9981" is not a small problem: http://trac.macports.org/ticket/39150
I see you have the latest portaudio version (19.20111121), but 19.20111121 _4 claims to fix the bug. See if upgrade portaudio effectively.

So how to solve this problem?
