OBS stops audio feed randomly - restart usually fixes it

It terminated the capture because you were exiting OBS.

We need a logfile from a streaming or recording session at least 30 seconds long where the issue occurred, to be able to troubleshoot. That logfile contains neither.
If you are using OBS' VirtualCam feature in a different program (like Zoom or Discord), OBS does not handle audio routing through the VirtualCam device. You'll need to troubleshoot with that other program and how it captures audio.
