Audio records when Debut=fullscreen, only... if then

[King-daddy]

New  Debut Pro V 3.07, Windows-7, audio default to speakers:

Steaming program-Video from video.theblaze.com;

The only time it records sound, Debut is set to record FULLSCREEN.

If I enable MOUSE, it has breaking-up, static noise in audio.

I tried reducing the quality of the audio, makes no difference.

The source is Full HD 1920 px. I have no options on the source, 30 FPS,

...but capture audio indicator is varying 11 - 16. (Is that video?)

My household Cable Service tests at 56 Mbps.

Note please:

This is the most difficult (to use) support discussion / forum package that I have encountered with over 37 years of professional computer support.  News-groups are king.

I've got it working most of the time. Much of the problem is me, assuming settings from last record attempt were still retained, and that's not the case for all settings. 

I still have occasional audio sync with video malfunctions;  Terminating browser and Debut Professional, then restarting solves the issue!
