1 Push on the Apple Pro Speaker jack to make sure it is firmly
inserted into the Apple Speaker sound output port. (The Apple
Pro Speaker jack has two detents. You should feel them as you
push the jack into the sound output port. Giving the jack a
slight twist while inserting it into the port may make a
better connection.)
2 Verify the speaker volume and balance are set appropriately
in the Sound system preference or Sound control panel and
mute is not checked.
3 Clear parameter RAM. Hold down Command-Option-P-R
during startup until you hear a second startup chime.
4 Reinstall system software.
5 Replace the Apple Pro Speakers.
