If you camera has mic, please follow the steps below to enable audio function on Nuuo:
------------------------------------------
Go to Setting and you could see “Audio Preview” under “General” tab.

1. Check Preview Active Channel, then you could hear the audio when you click on that camera.

2. Uncheck Preview Active Channel but select a camera in Default Channel, then you’d always hear the audio from that camera.

Thanks.
