Crackling audio while recording game using Loopback and OBS

[Nephelangelo]

I've been experiencing crackling in my audio while recording a game using Loopback and OBS, which is ruining my narration. I've swapped mics out and I'm still experienced the crackling. Not sure if this is electromagnetic interference but I sort of doubt it, I suspect it may have something to do with OBS. Computer is a new Mac M4 desktop. Audio is not clipping anywhere. I've swapped settings around in OBS trying to resolve this but have had no success, currently they are:

Hmm. Just replaced some cables and recorded again with Audacity as a backup, and the crackling has persisted, even in the backup audio. Maybe I need to update my drivers. Anyway, thanks for the help!
