About a month ago my Mac Pro 2019 running the latest version of Catalina started this strange behavior. Sometimes when I launch say a 30 minute Quicktime tutorial, it auto-runs through the entire video in maybe 5 seconds?

I finally found one thread on the Internet that suggested opening Activity Monitor, selecting "coreaudiod" and force quitting it. When I do that it immediately restores everything back to normal (as well as relaunching itself).

So, what is causing this to happen? It never did this for the past year until maybe a month ago?
