Hello, At the beginning it worked perfectly well, when I added an audio file (.mp3 or .wav) from my computer to a movie , but now when I add the music, it play the first time I play the movie, but if I try again, I hear nothing, despite the fact that the music is still present, I see it in the music line, but hear nothing when playing it and when I try to edit the music I get the message : no native sound or sound effect for the selection. When I add a music with smartsound it works fine. I'm very disappointed. Can you help me ? Many thanks ( I'm a French user, hope my English is understandable).
