Question / Help Audio Clicks/Pops/Stuttering

Hey all,

Having some problems with streaming on Mac OBS with the audio. The audio input (audio signal coming from my analog mixer), when monitored, or recording/streaming, is clicking/popping/stuttering at regular intervals. This does not happen if I monitor it in my usual DAW recording programs like Logic or Pro Tools. The audio levels are good (not clipping etc),

I am using a Apogee Duet as the audio interface, but I also tried another audio interface - Focusrite Saffire 24, and it has the same problem. So I think it's something to do with my OBS. I am on Mac OBS using a Macbook Pro 13".

Here's my changelog:
