Glitchy (echoey?) audio problems that appeared suddenly

[8ballposse]

Recently my OBS stream audio has started to glitch either immediately or after few minutes of otherwise flawless audio when I start a stream. I streamed for 2 years with this setup and experienced no audio issues like the issues I'm now experiencing now. I've noted a couple changes that were made recently but not sure if they would have anything to do with the glitchy audio problem.

Things that have changed recently:
-2 studio monitors plugged into a Pioneer DJM 450 mixer via XLR (previously I was using speakers powered from a receiver coming from my mixer)
-Changed a couple settings under Output/Streaming as suggested by a youtube video and unfortunately didn't keep track of what they were before and what I changed to.
-i know i changed CPU usage and Profile settings but not sure exactly
-lowered my bitrate from 3000-35000 to 1500 due to choppy video during stream
-Recently bought and plugged in a Logitech C920 camera, mapped it as a video source in OBS, didn't like what I saw, removed it from the source
-On "Stream starting", "intermission", and "stream ending" scenes i created a VLC video source that injects videos I have stored in a folder on my computer

I'm currently running a Macbook pro 2015 2.7 GHz Dual-Core Intel Core i5, Monterrey OS, 8gb memory, 40gb+ open HD space, audio coming from a Pioneer DJM 450 mixer, and using a logitech c922 camera.

I’ve been reading forums and people saying make sure all your audio devices sample rate are either 44.1 or 48khz. I can only find one setting in obs to change that sample rate. I opened Audio Midi Setup app on my computer and and saw my mixer is 48khz. I'm pretty sure I was running 48khz on OBS and experienced zero problems previously.

I'm starting to test USB cord issues. I have 2 usb cords I've use and the problem happens with both. Since both cords are present when the issue happens I'm guessing it's not a cord issue where both just happened to malfunction at the same time. But I could be wrong and ordered a slightly elevated cost USB cord and it arrives in 5 days.

Anyone have expertise or ideas on what might be happening?

Included 2 recent log files today as I was testing different audio and camera setups trying to pinpoint if it was usb cord or usb input problems.

Hi, I had a severe echo yesterday. Then went into all my scenes because I sometimes have implemented 2 mikes in one scene. I had the impression they were both recording at the same time, but processing just slightly after one another. I put one of them off and then the problem was fixed. But encountered another problem: Sound is only picked up from my MacBook built-in mike, not from the 'plug-into the MacBook mike'.
