audio reproduces poorly in timeline

Hello,

I hope you can help me. For some time, in all of my premiere projects, the audio reproduces poorly in the timeline, meaning it doesn't reproduce fluently. Therefore I can't use Premiere to edit even simple audio, because I have to export it to see how it would sound.

When I open the source in the project, there is no problem in reproducing it. I already tried pre rendering the audio, but it doesn't change anything. The audio is at 48000 hz, as well as the settings.

Thank you in advance!
