I have a project done completely from multicam clips. Everything is fine when I play the clip in FCPX 10.1.1 . BUT when I try to export using share (master) the sound is gone only a loud hiss can be heard. As I said in FCPX it plays perfectly fine. Even when I send the file to compressor the audio is gone and only a loud hiss is to hear. The project was over a weeks work and is finished ..... Any idea what can be wrong???

I work with FCP since over 8 years now, with X since 2 years., never had such probelms. I really need help !!! Thanks
