Just had my first 1/1 training at the Apple store on iMovie. Right at the end the trainer showed me how to drag music from iTunes into an Event - but it didn't work. It was the end of the session so we left it.
Now I can't record audio at all, and the audio on the clip I did in the tutorial has gone too.
I've set system preferences/sound to internal mic, Skype is working and recording fine, but still no sound on iMovie.
