Configure sound through camera (Lorex)

[opax]

Hi folks,

I'm in the market for new camera security app. I'm moving from iSpy and love Blue Iris so far. The one thing I need to get setup before I will pull the trigger is the talk over the mic feature. I have Lorex cams (LNW16XF) that have a talk feature. In iSpy I am able to talk using my computer microphone and my voice come out of the camera speaker. It seems that this feature is supported in Blue Iris, but none of the settings combos I've tried has worked. Is there any guidance anybody can give to help troubleshoot this?

Here is the output from the "Find/inspect" feature:
