OBS Hissing while recording on Lunar Client

[yeetbucket]

I have a problem. I try to record with Lunar client, and I have an annoying hissing noise within the recording. I have a really good computer, getting thousands of frames per second, but when I hit record, there is a hissing sound in my recording.
