[oneiric] no sound after headphones jack plugged in

[Ярослав Почернин]

I am using Toshiba NB100 Ubuntu Certified netbook. The sound works fine in general but if I plug in a jack it disappears. If I go to alsamixer I can see that the Speaker fader is down, so, if I move it up again, the sound appears in the headphones. But if I unplug the jack and plug it in again, the fader instantly goes down again and the sound disappears. This is a regression that prevents me from using Oneiric full time now. I've shown what happens after I plug in the jack on the attached screenshot.
