also, when open volume preferences, option 'null audio output' (or that; add exact words here once error again).
besides, in sound preferences, if choose device 'hda intel stac92xx analog (alsa)' , error message:
'audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink: not open audio device playback.'

btw, ever since upgraded jaunty, whenever try maximize media player, reverted login screen.
