I am guessing the hardware defaults to earphone until a switch in the jack tells the machine to go to the speakers, Not sure, I didn't take the ibook apart and don't have a schematic. Maybe the imac is similiar? next: All ubuntu installs I've done have had sound muted initially. Unmuting thi icon in the system tray didn't always work. I have had to mess with the mixer settings to get it to work, On a couple of machines albeit not ppc I have had to move a slider on the mixer to get sound to start after every reboot, FWIW this was not unique to Ubuntu, the machines did the same thing when I used Fedora Core.
