Comment (by drive4code):

 Update:
 I've tried using pcm_s32le and the artifacts are still there and in same
 amount. Howere, this command reduces the number of artifacts: vlc
 input_video.mp4 --sout
 "#transcode{acodec=s32l,ab=1411}:std{access=file,mux=wav,dst=output.wav}"
 vlc://quit

 I understand its from vlc, but I belive it uses the same libraries as
 ffmpeg and hopefully it can help diagnose the problem
