How do I playback my voice through my speakers?

IMovie Sound does not playback.?

• Hello! I'd really really appreciate it if someone could help me with this problem i'm having (: Basically, I'm creating a video for a school project, and it involves voice over. So I arrange photos, and I do a voice-over. It was working perfectly fine, until roughly 50 seconds into the video. When I voice-over the pictures, the sound gets recorded, but it does not play back. The sound for the first part of the video works fine though. I don't think the problem is really with the voiceover. I tried importing music files but they don't work either. Other things i've tried 1) Adjusting the recording/playback volume 2) Checking if my mac's speakers are fine (yes they are, i played music to check) 3) Checking if the mic is fine (yes it is! I can record and playback perfectly fine on garageband) I'm relatively new to mac, so i'm not very familiar with iMovie :) Please do help me with this issue, thank you so much!
