Why are audio and video out of sync when I use OBS studio with ClonerAlliance Chert 4KC?

Please set up as following and it will perform normally.

First, please set CA Chert sample rate as 48KHz.


And please make sure sample rate in OBS Studio is also set to 48KHz.


If your video and audio are still not synchronized, please adjust video delya value in “Source-filter-Video delay(Async)” arround 470ms according to your circumstance.
