Audio waveform not showing visually

Sorted!

I tried all the trash preferences stuff, nothing worked.

I solved by loading the audios on Audition, by simply clicking right button and Edit Clip in Adobe Audition. 

Old question, but I stumbled onto it today and found my own unorthodox solution after none of the suggestions here worked. Right-click the audio that isn't showing a waveform and click "Edit Clip in Adobe Audition."

If you're like me and none are showing: Select all —> Right click any audio file —> Edit Clip in Adobe Audition. That forced all the waveforms to show up for me. Then just crtl-z and they'll revert to their original titles/names, but the waveforms stay.

All these answer mean nothing. Adobe is buggy trash. Right click and render audio after clearing your cache and restarting.

So after trying everything mentioned in this thread and screaming at the computer... I noticed a little spinny loading thing top right of the screen (I'm working with big clips) and then I saw the "generating peak file" progress bar in this screen shot. My waveform wasn't there because I didn't let it load 🙊 sorry for shouting at you!

Hi there. 
Checking this post in Dec 2023 and man, this is still a thing!
Using Premiere CC 2023 up-to-date on a M1 Max 64GB computer and this is still going on!
In my case, specifically, I got to solve fast simply by closing and opening Premiere again, without even rebooting the computer.
Well, it's a good thing though this doesn't happen too often.

Cheers.

Using Adobe premiere CS4, right click on the audio track of the video and select audio gain. Next select set game to 24 DB for example, click ok and then it will rebuild the peaks to where they can be seen. It is very annoying thing to discover this almost 4 years after having the software but there it is.

I tried all the tips suggested here but the only thing that solve was: (For mac users)

- Close premiere Pro
- Go to Apps folder and find Premiere 
- Right click on Premiere icon / Get Info
- Mark "open with Rosetta"
- Open Premiere / open your project
- You'll see the waveforms showing up
- Close the software
- unmark "Open with Rosetta"
- Open Premiere again and it should be solved.

This type of error is a significant setback for video editors. Sad to still have to deal with these problems and palliative solutions that look more like a puzzle game 😕😕

Same for me along with audio random dropouts. I'll have waveform but no audio, then audio with no waveform, then audio and waveform together. Been fighting with audio drop outs for 4 months. Trashed Pref., and tried everything else in the books. Everything! I dont want to move to Resolve but I do need reliable software. 

Try restarting your PC. A good restart fixes many issues. I have this bug a lot and a restart fixes it most of the time.

Here's a fix that is not very satisfying, but it works every time for me, when I'm importing an mp4 video/audio into Premiere Pro. (Mac instructions follow). In the Finder, just open the mp4 file in Quicktime and confirm that you can play video and audio in Quicktime. Close Quicktime, then drag the mp4 file into the timeline in Premiere Pro. That's all!
