Bug#767239: Regression: T420 docking station headphone plug not working automatically



Hi,

the Docking Station seems to be following: http://www.thinkwiki.org/wiki/ThinkPad_Advanced_Mini_Dock

And the mentioned patch is the wrong one. I've tested it more and noticed that it also happens in 3.15 (before the patch was applied) - but not with 3.14. I've removed pulseaudio to better check the problematic. The used tool is called 'alsactl monitor'

Plugging the Laptop headphone jack on/off with 3.16 prints following:

card 0, #14 (0,0,0,Headphone Jack,0) VALUE

card 0, #14 (0,0,0,Headphone Jack,0) VALUE

Doing the same thing with 3.14 prints nothing.

Also plugging in the Docking headphone jack on/off with 3.14 + 3.16 prints nothing. Not sure what is the correct behavior but at least both jacks should either both generate some events or no events at all

No idea how to debug that further... but willing when somebody gives me some hints what to try next
