A few days ago, I did windows reinstall, so I had to install Pr again, cuz i don't know things about this settings, I left it like it was after installing, screen is here:

Create a new, empty sequence: File > New > Sequence.
Click OK when the New Sequence Preset Panel Opens.
When the new, empty sequence opens on the timeline, drag when of your video clips into it (it would be best if you chose a clip that has the same properties as most of the clips you plan to use).
You will be prompted to match the Sequence to the clip - click on Change Sequence Settings.
Now drag the wav audio file into the sequence.
Does it work as expected?
