I went through some drive problems and had to copy all my media from one drive to another and then back again. Everything is intact except there are a lot of audio clips that are silent. If I go to the first frame of the audio clip in the timeline and do a match frame, it brings up the source slip in the source monitor and it plays fine there. But the same clips in the timeline make no sound. If I match frame it and then edit it into the timeline, then it works.

I have a lot of clips like this in the timeline and they all have some EQ and level adjustments. When I replace the clips I lose those settings. I tried relinking but nothing relinked. Obviously the media is not offline or it would not show up in a martch frame in th source monitor.

Is there any other way I can get the audio back without replacing all the clips?

[EDIT]

I had an earlier version of the timeline and the audio is all fine on that one.

sounds like sequence corruption.  What if you cut that sequence into a new sequence?
