Instagram videos are muted, that's why

Most old Instagram videos have lost their sound. More than a year of video posts on the platform are now without sound, showing the text that the video has no sound.

The problem seems to affect videos posted before 2014.

It has been noticed that videos posted from June 2013 to October 2014 no longer have sound. The video's audio is not played on any device where Instagram opens, TheVerge wrote.

For Instagram users who have had this happen to them, losing audio can be a big loss. One of the reasons people post on Instagram is to preserve moments in time, and audio is often an important part of a special video.

Meta has said that it is fixing the problem, but has not given a date when it can be solved.
