Comment 9 for bug 349847

I had the same problem.
I used amarok 2 with Intrepid adding same repositories, and after a message "phonon, Pnp usb audio dosen't work, falling back to default" it worked fine. After upgrading to Jaunty, no message appear, and no audio on amarok (the track doesn't start to be played, and no on screen display show the track information, but down on the right, in the amarok gui, is showed the current track). The solution posted before (http://chanweiyee.blogspot.com/2009/04/ubuntu-904-amarok-2-sound-problem.html ) worked for me.
