replacing audio of a clip after editing on a timeline in Premier Pro CC 2017 I have a clip which I have edited on a timeline, I want to go back to merging a new audio file into the original file. I try merging the audio file into the original file but this creates a new merged clip which does not have the edits.
Your best bet is probably to replace the source of the clip in question with the timeline that has the changed audio.  There should be a "Replace Footage" option or something like that.  I'm only familiar with CS6 though, so I'm a bit out of date on exact specifics in the latest version of CC.
