내 GC553G2에서 4K60을 선택할 수 없거나 소프트웨어 미리보기에서 내 GC553G2로 캡처한 오디오가 정상적이지 않은 이유는 무엇입니까?

1. Make sure the version of firmare of your capture card device is up to date. 

For example, please ensure the driver and firmware of your GC573 are up to date.

Driver: 2/2/64/95
Firmware: 1.2 (20201015)

For GC551G2, please make sure the firmware is F1.2.5.9



2. It could be a USB3 compatibility issue(e.g., GC553G2, GC553, GC551G2). It's known that ASMedia's USB host controller may have this problem. Please switch to USB ports that are Intel or AMD native USB host controller.
(Notes: We have found some motherboard like B450, B350 series may have this compatibility issue)

3. This may be due to built-in AI noise reduction on your platform. Please turn off all AI noise reduction on the software such as NVIDIA Broadcast below:



Choose All off on Microphone arry in Realtek Audio Console





As for other PC manufacturer like HP or Dell, you can  see our troubleshooting tutorial video.

For ASUS motherboard or laptop, you can also choose "off" on their software
