Adobe Flash Audio Weird???

Hello, I've been searching for an answer on this but can't seem to find one. I set my audio to sync, and while the audio does play while I scroll through the timeline, the audio is completely messed up. It plays fine when I press play, and the mp3 file is just fine. I have what the audio sounds like here, no video to go with it though because my computer can't do that 💔 basically very... choppy, I guess.

ty for ur help ❤️ if you need any more information I'm happy to provide it 🙂
