[Python] PyDub: ffmpeg not found

I have pip installed python-ffmpeg and am trying to play a wav file with PyDub. I get this warning:

Warning (from warnings module):
File "C:\Users\divel\AppData\Local\Programs\Python\Python39\lib\site-packages\pydub\utils.py", line 170
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work


And then a permission error:

PermissionError: [Errno 13] Permission denied: 'C:\\Users\\divel\\AppData\\Local\\Temp\\tmp0t700dh0.wav'


Any suggestions on how to fix it? The code itself is:

from pydub import AudioSegment
from pydub.playback import play

snippet = AudioSegment.from_file('suoni\snippet6.wav', format = 'wav')
play(snippet)
