Double speed audio in recordings

H
Hello all, I have an issue with OBS recording.

While I´m using OBS for record my webcam and audio from mic (classic via sound card or USB) the recording is demaged. When I play recording, first 2 or 3 minutes are OK, but then the speed of audiotrack is doubled. Sound and video are asynchronised. I try to play the recording in VLC. The same issue is, when I import recoreded file to the Davinci Resolve. What should by the problem?
Can you advise me? Thank you.
