Controlling mic on floodlight camera

I have experienced a total drop of sound on the video footage being recorded by my floodlight camera a few days ago. I am wondering if this is a malfunction and warranty item or if there is a setting that I need to be aware of. Can anyone help me with this?

Hi @mmp. When you are accessing the Live View for your Floodlight Cam, please make sure the volume on your mobile device is turned all the way up and your phone is not muted. Additionally, make sure you unmute the mic after accepting the call by pressing the green phone icon and then the microphone icon to unmute. If you still do not have any sound after this, please reach out to our support team here.
