No audio after setup

[IJAM]

Today's update wreaked havoc with my sound.  I had sound cutting in and out so that no one could hear me.  I was greyed out for others.  Everything was working PERFECTLY up until the update.  Has anyone ever had an error "audio device IO is 99.79% unstable" or "Network Media Network Connection lost error"?  I have no idea how to fix either thing or what caused it, apart from updating. 
I'm running a new Mac mini and Scarlett Solo.
