Yes this patch is already included with kernel 3.19.0-13-generic It actually more of an issue with the audio control panel. The Mic is gray out. But after installing pavucontrol it start to work.
I think the bug now is fix. I reinstall using ubuntu daily 20150412 http://cdimage.ubuntu.com/ubuntu/daily-live/20150412/vivid-desktop-amd64.iso This solve the issue. The Mic is recognise and working.
