Hi there,

It is not a problem with your computers I'm affaid.
The videos are silent for two reasons. It is either to allow the teacher to talk them through with their students or for the students to work independently without the need for headphones.
Essentially we wanted to limit problems users could experience with using the videos. If they prove popular then we might do some voice over in the coming weeks/months…  I hope that you have found them useful! J

Many thanks, Mark

Of course!!!!   Now I see.  This is quite brillant.  I am so disappointed I didn't "get it" before.  I love it.  What a great opportunity.

I can't wait to share with my students.

Thank you for sharing!!!

These look llike amazing tutorials.  Thanks.  However, I don''t get any sound.   Even if I play on youtube.   I do get sound on other youtube videos.  Just not these.

Any ideas?   Anyone else have this issue?
