Comment 63 for bug 477226

Thank you Luke!
I added ubuntu-audio-dev ppa, installed those packages and rebooted.
It works now!
When I plug in my headset, speakers get muted and I can hear sound on my speakerphones.
But unfortunately my internal microphone doesn't work any more. External microphone works when I plug it in.
For me this is not a problem because I use headsets with external microphone.
So for me the problem is solved.
I can finally listen music in public places!
