1. The computer has a USB audio device and USB Camera device. Both of them are from one USB composite device.
2. In the built-in Camera application, Start and Stop Record repeatedly at short internals like 3-5 seconds.
3. Intermittently, after a Stop action, Camera Preview video shows some tearing/glitch.
This is by design of how Camera and USBAUDIO driver handles audio I/O.
