So I reopen my project and now when i play my video, the sound of the interview has been replaced by a song and another segment by a sound of birds, etc. The same audio file from an interview is lagging and replaying as many different sounds making my project impossible to work with. I tried replacing my clip with the originial file, no changes. Whats strange is that depending on the time what plays is a different sound from the project. I just cant find the original interview sound back.
