Spotlight Camera - No Siren, No Audio

Hello, Just completed installation of the wired spotlight camera. Solid connection, see it in the app, video works as well as the light. However, when I try to activate the siren in the app, I hear nothing. The app indicates that the siren is sounding and gives me a 30 second countdown, but the camera isn't making any noise. Also, when I turn on the microphone in the app, no audio comes out of the camera. Am I missing a setting or is this a defective camera?
