Sound in diaporama produced from the album

Hello,
Maybe I missed something but I did not found how to have a background music in the diaporama produced from the album. This is possible with the diaporama produced from the gallery. The best solution should, I think, to have a key to start/stop the music and an option to loop it. Has anybody a solution ? Or just a way to have music in the background ?
Thank in advance.
