Default [Q] HTC One M7: Fuzzy feedback on video recording

When I record a video using the regular camera app, it records fine. Then when I watch the video, I get this fuzzy feedback. I've tried using the Voice Recording tool and it works fine. I listen to audio on anything from Instagram, to YouTube to Facebook, and there are no issues. The only problem is the fuzzy and staticy feedback. If the speakers and microphone aren't the problem, what could it be? Thank you in advance.
