I just got this Yamaha Mt120 and there's no audio out. Slight hiss and that's it. It'll pop if I flip the monitor select switch but that's about it. Not sure what to do.

I recently got into taking photos using film, since I don't have that much experience I've been using generic disposable cameras. They all have turned out pretty good, but one came back like this. Anybody know what might've happened?
