I built a slide show with Pinnacle Studio 10 adding titles and transitions and a sound track from a DVD. I clicked the start button on the right hand top corner screen and it played well so I saved it and built a couple more slide shows intending to burn them at the same time. However, when I played the third slide show that I had built there was no sound. I opened the timeline view and could see the audio track. I then opened the change the volume of the audio track function and I could see the colour move up and down the right hand column.
I appear to have lost sound on all three slide shows yet all show the music when I open the timeline view and all show music when I open the change the volume of the audio track function.

Any advice would be welcome.
