If you don't hear sound when playing a video, try these troubleshooting steps:

1. Adjust the volume control on your computer and speakers.
2. Adjust the volume control located in the lower left-hand corner of the Video Player.
3. Make sure the the Video Player sound mute button is unmuted. By default it's unmuted.
4. Restart your browser.

If you still have no sound after completing the steps above, these additional tips may help:

• Update your Flash Player to the latest version.
• Allow third-party Flash content on your computer: Learn more by visiting Adobe's Help Page.
• Check any Antivirus and Firewall software to see if its blocking third-party Flash content.
