It most likely occurs if there once was an accidental interruption when you downloaded, transferred, or converted a file before. Besides, you’d better not download files from unverified and suspicious sources.

Cause 4. Your Audio Driver is outdated

This cause applies to any situation where you can’t hear the sound. Similarly, if any other hardware or software of your computer is outdated or damaged, you can’t play media files as usual.
