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.

With auto scalar function | YES! | NO Scalar !! HDMI input resolution and frame rate must be equal the UVC resolution and frame rate | YES! |
Advantage | It is very easy to use | 1. No scalar ic “ video distortion “ 2. up to 1920x 1080p 60fps YUV output | It is very easy to use |
Disadvantage | Video scalar ic distortion | It have many use limitation | Video scalar ic distortion |
