From one day to the next I do not hear any sound coming from the built in speakers on my PowerBook G4 1GHz. When I check the audio preferences, it displays Headset copnnected to the audio output as the chosen output and I cannot really choose anything else. I believe before it said always Built in Speakers there, unless I'd plug the Mac via firewire to an external audio module. Could it be that I lost or accidentally deleted some sort of driver or other piece of software necessary or is this some kind of hardware damage? (I haven't really using my computer as a freesbie lately!)
Thanx in advance, Atahualpa |

Sounds like poor contacts, dirty contacts, high impedance, dry joint ( poor solder connection ) etc. I know on ibooks there is impedance detection on the minijack output, this could be getting confused by dirt/oil/residue which would affect the output driver. Try a contact cleaner, non greasy.
Otherwise it's software based and a reset might do it. If the minijack has got an bad solder connection then it'll need opening up etc big bucks! -------------------- Simon Flinn
