OSError: ctypes.util.find_library() did not manage to locate a library called 'CoreAudio'

Getting this error:

`
OSError: ctypes.util.find_library() did not manage to locate a library called 'CoreAudio'

When trying to import soundcard into my project. OS: macOS

Any idea on how I can solve that?

I have solved it temporarily by following these steps

Seeing the same issue with the same OS version and python 3.8.6:

Traceback (most recent call last):
  File "sound.py", line 1, in <module>
    import soundcard as sc
  File ".venv/lib/python3.8/site-packages/soundcard/__init__.py", line 11, in <module>
    from soundcard.coreaudio import *
  File ".venv/lib/python3.8/site-packages/soundcard/coreaudio.py", line 16, in <module>
    _ca = _ffi.dlopen('CoreAudio')
  File ".venv/lib/python3.8/site-packages/cffi/api.py", line 150, in dlopen
    lib, function_cache = _make_ffi_library(self, name, flags)
  File ".venv/lib/python3.8/site-packages/cffi/api.py", line 832, in _make_ffi_library
    backendlib = _load_backend_lib(backend, libname, flags)
  File ".venv/lib/python3.8/site-packages/cffi/api.py", line 827, in _load_backend_lib
    raise OSError(msg)
OSError: ctypes.util.find_library() did not manage to locate a library called 'CoreAudio'

I have temporarily avoided the error by adding this code in …/lib/python3.8/site-packages/cffi/api.py

    if name=='CoreAudio':
        path='/System/Library/Frameworks/CoreAudio.framework/CoreAudio'
    if name=='AudioUnit':
        path='/System/Library/Frameworks/AudioUnit.framework/AudioUnit'

like so:

Hope it helps

I just installed Python 3.10.9 on my Big Sur MacBook Air, and ctypes.util.find_library() now works properly.

That’s very good to hear!

Since I don’t have access to a modern Mac, one of you will have to step in with a solution to the silence issue. I have no way of debugging this, unfortunately.
