Everytime I start my laptop and log in to KDE pulseaudio does not work properly. Playing mp3 just gives no sound (using mplayer). Playing movies on youtube or other sites gives no sound with the movie and the movie plays at very fast speed. But when I just do a 'killall pulseaudio' from a Konsole session everything suddenly starts to work. Automatiacally a new pulsseaduio process is started, mp3 plays fine and web video play smoothly with sound! Hope this may help. -Marcel -- ======-------- Marcel J.E.
