Weird game box sound issue while streaming

[Sojyom]

Hi,
I got this weird box sound while i streaming a game. Not always got this sound. Specially CS2 and now Fragpunk got this problem.
First link is the Fragpunk gameplay you can hear it while i was shooting or something happening there is a waving box sound. (This OBS session is the log file)
The second link is the CS2 stream issue.
