Why is audio randomly cutting in and out? How do I fix this-

Hello! I'm relatively new to Davinci Resolve, and I'm trying to make a project that involves a lot of simultaneous videos (with audio) all playing at once. For some reason, the audio keeps randomly cutting in and out, and I have no idea why. If any more clarification is needed to answer the question, please let me know.
