Nice shot! It appears to work. :-) No clicks, no static.
I had to apply it by hand over 4.1-rc7, because the first two arrays
look different in both it and -master. Anyway, I will play with it some
more today see if anything else is broken.
Oh, and yes, the second state is without headphones on. I removed them
without thinking when the noise started. Sorry about that.
Thanks!
