Describe the bug
Audio is not present in some videos downloaded. I am unsure if this is similar to other issues, since this happens for every 6-7 videos on my end. I have ffmpeg installed and am currently using macOS.

To Reproduce
Steps to reproduce the behavior:

video_path = f"assets/temp/{reddit_id}"
video_name = f"{name_normalize(reddit_title)[:251]}"
reddit = Downloader(max_q=True)
reddit.url = reddit_object["thread_url"]
reddit.path = video_path
reddit.filename = video_name
reddit.download()

video_full_path = f"{video_path}/{video_name}.mp4"

Videos that were downloaded without audio:
