Thanks for both of those inputs, Ronni.  No help either one, no sound controls 
showing.  However I think I have at last found the reason.  To get the sound 
you need a Gmail account, in a tiny little box, doubly small on an iPad mini.  
The material is a series of tutorials contained in a book that I read on Kindle 
for iPad.  The tutorials are “complete”but the YouTube videos go a stage 
better.  Funny, they show video but no audio.  
Many thanks
Severin
