Video and Audio Sync issue
UVC (video) and UAC (AUDIO ) is two independence stream. 
The output from uvc grabber cad is sync. 


After the PC cpu Process, it may have occur No Sync ISSUE. 

This event is the same as the uvc webcam ( logitech webcam, Microsoft webcam)

All of UVC device ( camera , grabber card...) have this Sync issue.  

It is due to the PC CPU process priority.    

It need the software AP to build the SYNC function for Audio and video 

Case 1: No SYNC function for audio and video

   For example: windows amcap (record),  MAC quicktime ( record)...

Case 2:  Own SYNC  function for audio and vide

  For example:  OBS, Live google hangouts Youtube , skype.....

  (The No sync event will be smaller)

UAC AUDIO "Bi Bi Bi..." issue
ddddd

The UAC audio "Bi Bi Bi...." is due to the sampling rate.




The sample rate of audio from the HDMI machine are  44.1khz  / 48khz.

The audio sample rate in the PC ( windows / MAC ) must equal the audio  sample rate of HDMI


For eample:


if audio  sample rate of hdmi is  44.1Khz and UAC audio  44.1Khz in the PC, the audio will be normal


if audio  sample rate of hdmi is  48Khz and UAC audio 48Khz in the PC, the audio will be normal


If audio sample rate of hdmi is  44.1Khz and UAC audio  48Khz in the PC, the audio will happen "Bi Bi" noise.


If audio sample rate of hdmi is  48Khz and UAC audio  44.1Khz in the PC, the audio will happen "Bi Bi" noise.
