If you or your students notice that your videos are muted by default, this is a browser specific setting. Unfortunately we don't have the ability to override local browser settings, however you can encourage your students to enable audio for your site! Once audio is enabled in your browser or for your site, this setting will apply going forward, so you should only have to adjust these settings once in your browser.
Here are some helpful instructions for adjusting browser settings:
- How to Allow or Block Sites to Play Sound in Google Chrome
- What to Do If Firefox Won't Play Any Sounds
- Allow All Auto-Play in Safari (this will allow autoplay videos with sound to play)
