Hello!
I have several mp4 files with clear audio and when I upload them to iMovie to create to a video, there is no audio on playback. I've tried restarting both my computer, the app, as well as creating a new 'movie'. No luck. I also deleted the app and reinstalled. Google didn't have any answers and neither did my tech friends... so help?

Not all Mp4 works with iMovie. It needs to be Mp4/AAC. AAC stands for Advanced Audio Coding.
Try converting your troublesome clips to H.264, Mp4/AAC with the free download, Handbrake. Do that even if the codec already is indicated to be Mp4/AAC. Re-rendering often cures the issue.
You can get Handbrake here:
A simple way to do it is to open Handbrake and do a File/Open Source. Navigate to your video and choose it as the source from the resulting screen. Then do File/Start Encoding. Wait a couple of minutes for the conversion to complete. Then save and import the converted clip into iMovie. Now see if you get sound.
