OBS Studio with CQ18t. Help setting up

Hi there.
Im looking for help in getting the cq18t to work with OBS studio.
Ive been using obs to livestream with other sound cards, so know how to geneerally set up things on obs’s side for livestreams.

But i just cant seem to figure out how to get the audio from the cq18t to be heard in obs studio.
I was hoping someone here can help.

-I’ve installed the windows driver for the cq18t.
-The cq18t usb is currently configured to 48khz, and Stream Mode: Stereo
-I can playback audio from the computer over the usb cable to the cq18T usb input. And it shows up as an audio option in windows settings.

Also, on the advanced audio properties panel in OBS, i see an option only for channels 1-6. Does that mean i wont be able to stream the BT or USB input over obs (if i dont use the stereo mode)
