Getting sound clips to play on successive slides in Keynote
When I insert an .MP3 or .MP4a. sound clip into slide #1 it plays fine, but when I insert the same clip into successive slides, it won't play. If I begin at slide #2, the sound clip plays, but won't play in successive slides after that. The same holds true if I start at slide #3; it plays, but won't play on slide #4, or slide #5, etc. What setting can I use to get the same sound clip to play on each slide? Thx.
