I've seen other people have had this problem but I haven't been able to fix it. It doesn't bother me too much when animating short stuff, but it's getting hard to animate long stuff.
Where ever I start playing music in the timeline the music always starts over. I have Adobe Flash Pro CC and a Windows 8 64 bit computer. PLEASE HELP!!!!
Are you able to post an FLA here that shows the problem? That would make it easier to tell you what to try next.
Go to the keyframe where your sound file starts. Select the keyframe and look at the Properties window. At the Sync: pulldown select "Stream". Make sure that the Repeat option is set to X1.
Sorry for the inconvenience. We are looking into this issue TristLK. We have been able to reproduce this issue locally and are in the process of fixing it. We will share more updates soon.
