Please excuse my dumb question, since Parkinson's I am forgetting basic settings and how/why. I don't remember changing or having a reason to change.

VMIX: Master Output set to Cable input (VB-Audio Virtual Cable) Headphones (Rode mic)
Camtasia: Microphone and System Audio ON: Mic records, no system audio appears.
Camtasia Tools - All checked.
I tried Master Output to Speakers and Default Windows and got system audio and unusable reverb loop.

I've been recording Vmix in Camtasia for years. Now I can't make it work. I think it has to do with Virtual Cable.
HELP!
