So I want to pause the audio midway, and play it again from where I left off, but it doesn't let me do that. It plays the rest of the movie without audio. So I would have to rewind the whole animation to hear it. This makes syncing animation pretty hard. Any ideas on how to fix this?
It sounds like you have placed the music into a keyframe on the timeline of your movie. Go to that first keyframe and select it on the timeline, then go to the Properties window. Set the Sync option to Stream. This should allow the sound file to work as you want.
Helped me out a lot!
