Help with external microphone not transmitting audio through Blue Iris

Please forgive the photos of a screen; it's from a server not connected to the internet.

I would really appreciate help with how to properly connect an audio interface connected to Windows to a camera in Blue Iris. Blue Iris version is 6.0.1.6. I'm very new to using Blue Iris.

1. The mic and interface works in Windows, I'm receiving audio.
2. The mic shows up as selectable under Other DirectShow devices.
3. The camera I assign the mic to does NOT allow me to select "Play Live Audio" when I right click it, and does not seem to be transmitting audio when viewed in Blue Iris/the web UI.
4. If I enable the built in-mics on the cameras (Reolink RLC-820a), audio is transmitted and works fine (but without being the mic I want to use).

I hunted through the manual and saw "If this option is unavailable, you may have enabled the automatic management of live audio from the selected Camera on the Cameras page in settings", but didn't have any luck with toggling and untoggling the "Auromatically play live audio on selected camera; mute others" in that section. Is there anything else I'm missing?

I would be eternally grateful for any help!
