No sound on video or on video messages

There could be several reasons why you are unable to hear sound in videos that are sent to you. It could be due to a problem with the audio settings on your device, a compatibility issue with the video format, or a problem with the video itself. I would recommend checking your device's audio settings, ensuring that the volume is turned up and any mute settings are disabled. If the issue persists, you may want to try playing the video on a different device or using a different media player to see if that resolves the problem.
