Hi, 
I am just getting started and watch the how to videos. But there is no sound! The sound is fine elsewhere on my PC. Please help!
Are you trying to watch them while you have Cubase open? This could be the problem.
If you tick the Cubase preference “release driver in background” you should be able to switch between them and cubase and hear both…just not both at once.
If that’s not the problem then give some more info on your computer, audio interface etc.
