Wave forms are not showing up!

I’ve been using KDL for a while now, but starting about a week ago, when I import a video with audio, NEITHER wave form shows. The video plays fine. I can edit fine and render without issues.
But not seeing the form is really restrictive. Did I click on the wrong button?
I’ve uninstalled. Re-installed, gone back to earlier versions and no fix. Help please

Hello @Grant_Holmes
At the top of the menu bar (or whatever it’s called), go to Timeline (left click) and select:

“Show Audio Thumbnails” (the 6th from the bottom).

Thanks Micha!
Any idea how that gets shut off?
