If your video doesn't have any sounds, then please follow the following steps in order to troubleshoot the problem:
1. Sound settings: Your video's sound isn't working might be due to the audio being turned off on the video player. Hover over the speaker icon on the Viostream player to see if there is an "X" over the volume icon. If yes, then click to unlock the audio icon and slide it to your desired volume level.
2. Sound card: To check if it is a computer sound card issue, please visit another site to see if there is audio player on other online videos. If all other videos have sound except for Viostream, then your sound card has nothing to do with the no sound problem.
4. Download your Viostream video. If you are tried all of the above suggested solutions, please download your video from Viostream. If the downloaded video doesn't have sound, then please check your source video if it has sound or not.
If you are still having audio issues on your video, then please reach out to our Viostream support team
