Audio waveform not showing visually

Right click > Render and replace. Try that!

(You might wanna unlink from the video clip first)

In my case I had a sub-sequence with an (although unused and not asigned) Audio Submix Track. Deleting this track in the sub sequence solved the problem. Not sure, but maybe PP takes the waveform form the "last" audio track, independently from what channels are really active and heard in the sub sequence.

I went through all of the "fixes" and nothing worked.

What did work was rendering the audio... with the audio selected, Sequence>Render Audio... 

Boom, immediate fix.

So I just got this problem, I think it might be linked to file size. 

I am working with a WAV file of 334 MB and there is no wave form showing, but I grabbed several audio tracks from other projects that are below this and all the waves generate fine in the same project.

i did rename the original file and it works for me try it 

this just had this happen to me today, the easist way I found that worked so far evertime is to 

1) make the clip offline

2) rename the audio clip in the folder

3) then go to the original clip in your project bin and right click and click replace footage with the new named clip.

Here's my solution: 1. Close out of Premiere completely. 2. Perform a search for all .pek files on whatever drive space your projects assets are located and delete them. 3. Launch the project and you should see Premiere generating new .pek files. I find it best to let your machine idle and allow Premiere to devote it's bandwidth to the task at hand until all .pek files have finished generating.

This has been a problem for me over the years where I lose the wav forms on the timeline, sometimes seemingly at random. Today it happened when I migrated a project and all it's assets to a new drive with more disk space (6TB of material on a 10TB drive). I came here to see if there were any updates to a solution since it's a pretty common bug from what I can tell. All of the .pek files were still alongside their respective counterparts, but using all the tricks in this thread I still couldn't get Premiere to recognize them. The deleation/re-generate method contiunes to be my best solve.

Found a silly trick : if you have the full Adobe Suite, from Premiere timeline (or project bin) right click to open up your sound file in Adobe Audition.  The operation made the waveform appear for me.  You can then simply close Audition and return to your project.

Restarting program fixed it for me
