So Im editing in the new 2022, updated Geforce drivers (2070), 128 GB of RAM, i9 9900k...
It's a theater production... so there are a lot of times where I can just speed through a camera angle.
Typically use JKL editing here... but every other time I start the playhead, hit L L ... it just takes off without responding to either spacebar or K. It will run on for about 5-10 seconds not responding to any commands.
If that doesn't work, try resetting the Workspaces: Reset a workspace Reset the current workspace to return to its original, saved layout of panels. 1. Do one of the following: • Click the Workspace menu icon and select Reset to Saved Layout. • Choose Window > Workspace > Reset to Saved Layout. from here: https://helpx.adobe.com/premiere-pro/using/workspaces.html
If that doesn't work, try Preferences > Audio Hardware and set Input to None.
If that doesn't work, try creating a new project and import the old one into it.
