I was looking on eBay at iMacs (this one is a white 24" 2.16 C2D.), and I found one that read:
The sound circuitry works, as the machine makes the normal startup chime through the internal speakers. However, because the headphone jack is apparently damaged, the machine believes that there are headphones connected. This causes the OS to disable the internal speakers in favor of the non-existent headphones. The sound control panel does not allow switching to internal speakers. Someone with the time and talent to repair or replace the headphone jack on this machine could possibly resolve this issue, as the internal speakers do work, as does the sound circuitry, as evidenced by the startup chime mentioned previously.
What can be done?
