Screenflow 10 audio issues

I have spent a lot of time on this issue and also conducted a search here. I have the most recent version of Screenflow. I haven’t used it in awhile but want to create a ‘vodcast’ for my students yesterday. I was not able to get the driver to install for computer audio. Well, it told me it was installing but when I tried to select computer audio, it didn’t realize I had already done so.

Apparently this is a known issue. I deleted and reinstalled the app. I deleted and reinstalled the driver.

My university is all in on Panopto but I really prefer Screenflow. Any clues to how to make it work? As a music professor I would like the option of recording computer audio.
