Windows 10: Why does my USB 3.0 HDMI CAPTURE CARD only show as a microphone in the Streamlabs

This is the screen of stream labs everything works fine but my laptop hp envy recognizes this as a microphone so no audio in the audio mixer

Game Card Capture HDMI/USB

So I am trying to plug in my game capture card, I have 3 different kinds, and none of my streaming programs are detecting any of them. I have tried all 3, many different ways as well as unplugging/rebooting everything. Am i doing something wrong? Is it my computer? I just streamed my switch using one of the game cards on my HP laptop the other night and it worked fine. I just got a new All in one HP desktop and it isn't reading any of the Game Capture Cards. I've tried hdmi port, USB, SS Usb, as well as a new one that uses the USB and plugs directly into the switch (I watched a YT video on it and did the steps exactly like the guy and it still did not work). Is this desktop just not compatible with Game Capture Cards? I also just used HDMI to HDMI directly from the switch to the desktop and obviously that did not work either. Help!

 

Trouble getting a capture card working

I installed an Elgado 4k HD capture card and haven't been able to get any signal from the input. It is recognized in the device manager. So I open the 4k capture utility which tells me 'device is in use by other software' or if I open Streamlabs OBS and go through the steps to add a source the card just doesn't appear. I've gone through all the troubleshooting I could find as relevant on both Elgado's and Streamlabs website and haven't been able to find a solution. Help in diagnosing or getting it working is appriciated

As far as mfg and model info of the device, In have 2 but they are both fairly generic from Amazon (got the 2nd I as I thought inncorectly that the 1st one was faulty) This is the first one :- DIGITNOW! Audio Video Capture Card, Full HD UP to 1080P HDMI to USB 2.0 Live Video Recorder Game Capture Card for Live Broadcasting, High Definition Acquisition This is the second one :- Papeaso Video Capture Card, Video Recording Card Wonderful 4K HDMI to 1080P USB C for Gaming Streaming TV Recorder, for Windows Mac OS System with USB C Adapter to Adjust PS4, Switch, Xbox1





- - - Updated - - - Update on this issue, I have now come to the conclusion that it is NOT the USB Capture devices that are causing the problem. I have unpluuged capture device and just plugged a couple of webcams in which are both working fine with the Windows camera app, but not working with the capture software which they should do. Suspect it may be either my ant-virus (AVG) or a setting in Windows itself that is causing the issue,thought I had covered those options but looks like I have missed a setting somewhere, will try again tomottow.
