are you sure you've installed all the correct drivers? I remember my aunt had a problem with the audio output and it turns out she didn't have the right driver installed on the system.

Huh? What drivers? This is a Mac. Even with OS 9, sound just works out of the box. This could be a logic board problem or damaged headphone jack.

just check to see if your sound is on in your system preferences... most of the time its a simple thing like that...

I was having this same problem on a G3 Snow. Took the whole thing apart and couldn't find any problems. Speakers listed in System Profile, but not in the audio output list. Worked on headphone, but nothing on external speaker or internal speaker. come to find out, someone (KIDS, gotta love em)had stuck a pencil into one of the headphone jacks and a piece of it had broken off in side. just enough to keep the contact open to the speakers. Used a long dental pick with a short hook on the end to dig it out. Works fine now.
Although most of these problems are just dirty contacts in those headphone jacks, which can sometimes be solved by repeatedly pushing the headphone jack in and out fast several times in each, You migh also want to check to be sure there is no foreign material in the jacks.
Hope this will help someone.
