No, 4.0.5 and all previous kernels (>= 3.12) are OK. I have attached a small tarball with the two files produced by alsa-info.sh.
Both are taken in different states (one is headphone plugged and another unplugged?). At best, take the snapshot in the same situation for comparison.
In anyway, below is another shot in dark. The white noise is possibly the ill side effect of analog loopback. But it's strange that this didn't happen on 4.0.x. And, it combines another black magic that worked for another Dell model. Let's see.

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!
