I’m kind of a novice at this, but yesterday, I made a Flash file using CS4 with some simple animation and sound. The sound was a mp3 I found on the internet. I used on-line videos, one Adobe and another just YouTube to learn the Actionscript 3 to make it work. Then I embedded my file in a PDF and it worked fine. It also works fine in a browser. I tried bringing the Flash file into an InDesign file and exporting it to Digital Editions. The animation and buttons worked but there was no sound. I’m using a IMac. Can you tell me what I’m doing wrong?
