I can confirm this patch works for me (adapted, because I obviously use some different kernel version). It seems I do have some bugs within my UCM file currently as the activation works but not deactivation of the headset. But "alsactl monitor" is fine and shows both events, insert and remove. *thumbup*

Next thing is the 4ch capture which hits me, too, like you described in your pull request. 

Curtis' goal to have their UCMs upstream also sounds promising.

Thank you all! My question here was more productive than I would dream of.
