I guarantee that there is no problem with my operation. I have tried every audio. I can't use it after purchase. I can't monitor and record audio. Please check it

I buy action! It has been a year since I paid attention to the update. Now I upgrade to 4.23.0. I still can't get the sound using AVerMedia gc555. I guarantee that there is no problem with the sound. OBS and bandicam can record the sound normally, including monitoring. I urge you to fix this problem...
