I upgraded to iPhoto 9.5. After converting my old iPhoto files to the new format, musical background was lost in all my slideshows and I can't recover it. I also can't add music to new slideshows. "Play music during slideshow" is checked, the source is iTunes, I select a song, click "Choose," no music. I'm on iTunes 11.1.1 and it's working properly. It appears the link between iPhoto and iTunes is broken.
