My indoor pan and tilt has lost sound. How do I fix it?
Well, just check the normal stuff in the app make sure record audio is enabled and if it is turn it OFF, and then turn it back ON. It might fix it?
Also try Restart Device if that option isn’t available in the app, then unplug the camera for a few minutes and then plug it back in to see if audio returns.
When in Live View can you hear audio sound?
