I have inserted some mp3 music to start with a certain subset of slides within the slide show of 200 slides. I used Audacity to adjust it to synchronize with the 10 or so slides within the overall slide show. It all works fine. But when I click on the waveform button in the timeline view, the waveform does not appear below the slides. Shouldn't I be able to see the waveform of the music I inserted? I have PTE 6.0.4. Thanks and regards, JBB
