Like the title says my powerbook no more makes the Dooong sound at start up or restart. I tried repairing permissions and looked into the system preferences/sound. Everything was like it should be. Sound is turned on and I have no additional speakers connected. The internal speakers are ok because I can hear other system sounds/music etc. It's not like the Doong would be extremely important, everything else runs fine. I just have a little time right now so I thought I'll ask the experts. Edit: I'm running 10.4.3, other specs of the pb see sig.
