There are many reasons you may not be able to access the video – the most common one being bandwidth/internet speed challenges. If you’re having technical difficulties watching the video, check to make sure your computer is properly updated, and your internet connection is running smoothly. Restart it. Try a different browser or device, the videos will play on tablets and phones as well as on computers. You can also try closing other programs on your computer that may be taking up space and slowing down speeds.
If you can see the video, but the audio doesn’t come through, check the following:
- The volume is turned up.
- Your computer or device is not muted.
- On a PC there are multiple volume controls.
- Do you have something plugged into the headphone port?
Lastly, each video has its own, hidden sound control. On a computer you start the video and then place your cursor over the video. Then move it to the left of the time display and the volume control pops up. This controls the sound volume for that particular video in that particular browser. On mobile devices volume control may work differently; try it out. The volume is always set to full, but it is possible that you accidentally lowered it.
