If you are running the GNOME desktop environment, start the volume control application (from Applications->Sound & Video->Volume Control). Select the "Switches" tab, and make sure that the "External Amplifier" checkbox is checked. Then you can experiment with the volume controls. Oh, by the way, to see the "Switches" tab, you might have to go to the volume control preferences and check the "External Amplifier" checkbox there too. :) The external amplifier is turned off by default in FC4.
