I've bee working on a project, when suddenly i notice the audio was fading in and out on all tracks at the same time.(two cameras and two audio devices) I rest all the audio tracks and no change. I replayed the original files both with an external program and MEP preview mode and the problem isn't there, the file plays perfectly. I replaced the file with a re-imported file and the track will play fine once then the problem will return in the exact same place. Viewing the audio meter in the Mixer, I can see the volume meter moving in the track during problem but no movement on the master volume meter. I can however make the audio play correctly if I import two of the same files, the problem seems to stop, however if I mute the volume on one of the tracks, like track 2, the original file with the problem and let track 9 play the second imported file, the problem returns, but if I play both audio tracks at the same time then the audio plays normally. This problem also occurred on two other imported audio files from a media device, again the file plays fine in both preview and external programs and has happened in the exact place in the time line, and again if I import the file in another track and play both at the same time the audio plays fine. If you copy the clip to another track then problem still occurs, only importing the file will work.

All the audio previously to this problem area plays normally, I've restarted my computer to see if that corrects the problem but nothing changes.

Any thoughts?

Thanks
