fixing stupid sound breaking on upgrading kubuntu packages

So I use kubuntu on my desktop, and it works great most of the time.  However, periodically on upgrading a package automatically, the sound just stops working.

Twice I've fixed it after extensive search, but I never remember how.  This post is sort of a public post-it note.  Here's how you fix this thing if you have a system like me.

Open alsamixer in a terminal, use the right arrow key to go all the way to the right, and mute (not unmute) the Audigy A line by hitting "M" on the keyboard.  This works for Soundblaster Audigy

Hope this is helpful to some other person tearing out their hair.
