You normally should never have any good reason to graphically log in as root.

My card does show the same in sndstat and is working great (SB Audigy).

Thanks Bruce, that did it. I no longer have distorted sound. Terrific :D </quote> So check that please and change the setting if you find it either in gnome volume manager or alsamixer in terminal and see if that changes the sound quality. > e) tvtime (see below) > f) General strangeness: As user I still get event sounds after I have > muted everything in > alsamixer - volume control.
