Good Morning Forum and OBS Team!

I'm looking to see if anyone can help me identify and correct this crackling/gurgling sound in the backgorund of my streams.

Here is a recent stream where it happened - Fast Forward to about 3 minutes to hear it:
https://www.twitch.tv/videos/231185778

Also,
here is my log file:

Unrelated to the issue.

You are launching OBS on your onboard iGPU instead of your 1050, this is causing OBS to choke
rendering the scene because the iGPU isn't powerful enough.

22:38:11.355: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 12821 (5.0%)

I realize this is a laptop but you can force it to run on the 1050 at all times

As for the audio issue, your OBS is set to 44100Hz, are your Elgato and your other playback/recording also set to 44100Hz? (Windows Sound Devices, Properties/Advanced for each device)
