There should be a switch for external sound that you have to press. Click on the volume button and then click volume control. Then click preferences. Somewhere under switches there should be an external sound thing, checking this only ADDS it to the volume control. After you add it, then you need to go to the switches/options tab and select it.

THAT is what I was thinking of. It's like "jack" something or other. Unfortunately, I don't have my Linux laptop up and running right now (Karmic tomorrow!) so I can't look at it directly.

jack is something else entirely

it is called external amplifier
