I just purchased an Arlo Pro camera to add to my current 3-camera system, and everything but the audio feature is working. I can hear activity going on around the camera, but it is impossible to talk back to it. The icon for audio is greyed out and just doesn't appear to activate. The "press to talk" feature never turns green or works at all. It appears this has been a problem before but has been fixed when others have reported similar problems. I have tried the fixes suggested and it just won't work.
