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! --=20 Mihai Don=C8=9Bu
