How to enable sound in embedded YouTube Videos on an iPad

I have embedded some YouTube video's in a course which play fine when I'm on a desktop computer or a Chromebook but not on an iPad. Before I submitted this topic I did one more search to see if it was an iPad problem and not an OpenClass issue and I found this solution:

If you set the Side Switch to Lock Rotation in Settings, the video will have sound. If it's set to Mute, you will not have sound on embedded video's. This issue occurs with video's in Facebook or even the Chrome browser on an iPad.

Just thought I'd share this in case anyone else has this issue.
