When recording the sound when capturing a video streaming from a site, the right mic must be chosen in preferences, that is, the system mic and neither the headset mic nor the internal mic. Then it will record the sound together with the its video.
But there is another problem that I have not been able to measure (if possible at all), that is, you have to first start the video and then begin to capture, mark and start recording it with Jing which causes a miss that at the fastest hand is about 5 seconds.
It seems impossible to record the audio together with the video when you are trying to capture a video streaming from a site. The mute button is not checked and it shows "Mic On" at the beginning. The mic is chosen to headset a mic in preferences and a sound in the control panel.
