The audio playback device HDA Intel (ALC883 Analog) does not work.
Falling back to default
I did a little google, and followed a post to change the backend from phonon-gstreamer to phonon-mplayer. Then, if I open Konsole and type 'mplayer some.mp3', sound comes. But, if I launch Amarok or Kplayer or something else, there is no sound.
What maybe is the problem, and how can I fix it?
