I have a curious problem with my work PC. It occurs with any video I've tried so far. Scrubbing works smoothly, but when I hit play in timeline, the playhead starts jumping a few frames back during playback. There is no apparent load on system (memory, CPU or SSDs), I have Ryzen 7 2700X (8-core) CPU, 32GB of DDR4-memory, RTX 2080 Ti adapter, two SSD disks, a 4K and a FullHD monitor. Videos play back just fine on Windows. I've tried several codecs, wrappers and resolutions, they all behave the same, even a 720p video.
Any ideas? I didn't find anything on Premiere settings that could cause this. I've also flushed the Media Cache (in fact I completely relocated it and deleted the old one).

Try resetting the preferences:

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.

If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site.
If that doesn't work, try creating a new project and import the old one into it.

Hi, I got the answer from the Adobe User Group Finland: In the audio preferences I had microphone defined as audio input. When I disabled it, things started working smoothly.

THANK YOU!
I could not for the life of me figure out why this was happening.
