I have no audio when I use time-lapse recording function, why?

When Time-lapse Recording is enabled, CyberLink YouCam takes a series of snapshots at specified intervals. These snapshots are then placed together in a video file, creating a video that uses time-lapse photography.

Please note that during a time-lapse recording, audio is not recorded and the time-lapse effect is only viewable after the capture is complete.
