Hello,
so far I love blue iris 5 still figuring everything out, however I've multiple TP-Link tapo C520WS cameras with talkback function. I can hear the audio from the camera but I can't talk, the microphone is green however not sound coming from the camera. Howver The blue iris websierver is on a pc where I didn't have anything audio related connected, there are not even audio drivers installed, could that be the issue, because the audio from the app is by my guess just passed through to the server.
Best Regards
Hunter
