Why do I not hear sound for my training videos?

If you are experiencing audio issues when playing eLearning videos, it may be related to a setting for autoplay.

Also check to make sure your sound is not muted.  For example, some browsers (such as Chrome, Edge, or Firefox) have a control for muting sound on the browser tab.  Right clicking on the tab shows a menu with a mute option.  In Windows, pressing Ctrl-M may mute / unmute the sound in the browser tab.
