I started a project a while ago, with a bunch of different videos edited together with a song overlay. Every time I open the file now though all that comes out is static. I've tried using headphones, opening the file through a different app, even deleting the song to put in a new one, but nothing works. I know its not a problem with y computer speakers because they work right for everything else. I'm pretty sure its some error with the software but I'm not sure how to fix it. I really don't want to start over as I've worked on this video for a few months now. Is there any way to fix the audio?
