Well, I'm an end user, not a kernel hacker, so I don't see it getting fixed any 
time soon. :)

Notebook: yes
Internal 5.1? I don't believe so.
Headphone, mic, line in? Yes.

Are you saying there is a large range on the internal mic? or on the USB mic?

> 2) your 5.1 internal speaker have same priority
Which priority are we discussing?  Somewhere in udev?  In pulse audio? Or in 
the KDE audio setup?  And this original thread wasn't about speakers.  The USB 
out works fine, every time.  My issue is this: when I try to hotplug the USB 
headset, it comes up as a *output* device only, instead of also detecting the 
mic.

Also, this worked flawlessly in Ubuntu 12.04 (pulse-audio 1.1, kernel 3.2-3.8). 
It is only since upgrading to pulse-audio 4.0 and kernel 3.13.x that i have a 
problem.
