Question / Help Line 1 (VAC) Audio not working on OBS?

[Chazzz]

So I use my blue snowball into audition and have a bunch of noise reduction and other settings on, and use VAC (virtual audio cable) as the output. It's on blue snowball stereo input, and Line 1 stereo as output. I have the Line 1 (which is VAC) as the mic/sux default plugin on OBS. I've been doing this forever, but I just updated my windows and now it doesn't work. It just doesn't come thru to OBS at all. Idk if it's something up w line 1 or audition or OBS. Can someone help? And yes I'm on 1.16.2
