Respuesta rapida
If an X video has no sound, paste the exact public video post URL again and check that the post is still accessible without restrictions.
On X, some posts expose different media streams depending on the post context. A wrong URL or restricted post can break the expected audio output.
Why the audio can be missing
Audio can be missing if the recovered public stream only contains video or if the shared post URL was not the correct one.
- Copy the exact video post URL.
- Avoid truncated links or incomplete embeds.
- Check that the post is public.
How to validate the correct X post
Open the URL in a private browser window. If the post does not play the full media publicly, the downloader cannot rebuild the audio layer.
- Use x.com or twitter.com.
- Avoid internal previews or cached links.
