Removing Squirrels Audio AirParrot 3 - A solution
I trialed AirParrot but it didn't work the way I wanted it to (it took over too much control of my laptop). So I uninstalled it. However even after removing it, if I used virtual meeting tools my audio would still switch over to AirParrot and other participants could not hear me.
I tried several things, searching the /library folder and others. I finally fixed it by re-installing AirParrot and then from the application's preferences panel clicked on "uninstall audio" and "uninstall video" drivers. I restarted my computer, removed the demo app, and this seems to have fixed the problem.
I'm sharing this for others who have experienced the same problem.
