Garbled audio in Quicktime recording

[elwittlif]

I'm running into an odd problem and I'm not sure where to start troubleshooting, because there are a lot of moving parts.

I use Soundflower to record system audio in Quicktime while recording my screen. What I'm capturing is video game footage, a game called Rimworld that I run through Steam. Occasionally, the audio quality shifts dramatically somewhere towards the middle of the screen recordings. It becomes garbled and unusable, and remains that way through the end of that particular recording.

Here's an example of the game's general environment tone...

And here's the same tone when the audio bugs out...

I know there are a lot of variables here, but based on my description and on the audio samples, does anybody have an idea of what could be going on?

Any insight would help, because right now I don't even know where to start looking.

Check if there is a difference between the audio formats in your set-up.
I am encountering similar issues and i believe it's due to the fact soundflower is locked on 32-bit while my physical interface is 24-bit.
I have no solution for this yet.
