find_library is failed to get the sndfile #258

This issues has observed while importing soundfile module at arm64 target. target runs on Python 3.7.4.

Soundfile.py is unable to get the sndfile but the same /usr/lib/libsndfile.so

linux$ python3 test_imports/test_audio.py
Traceback (most recent call last):
File "test_imports/test_audio.py", line 5, in
import soundfile
File "usr/lib/python3.7/site-packages/soundfile.py", line 142, in
OSError: sndfile library not found

So, I tried ctype.CDLL instead of find_library
-- _libname = _find_library('sndfile')
++ _libname = ctypes.CDLL('libsndfile.so')
++ print('Library: %s' % _libname)

But it is failing to open the _libname

linux$ python3 test_imports/test_audio.py
Library: <CDLL 'libsndfile.so', handle 3a832320 at 0x7f97cf0b50>
Traceback (most recent call last):
File "test_imports/test_audio.py", line 5, in
import soundfile
File "usr/lib/python3.7/site-packages/soundfile.py", line 147, in
TypeError: load_library() argument 1 must be str, bytes or bytearray, not CDLL

Any proper fix for this?
