And I've had the external speakers jacked in both in the front "headphones" jack, and the traditional one in the back, and sound comes both out of the external speakers and a speaker inside the machine.

sound cards have a myriad of different ways they can be connected to outputs.... its possible your motherboard's audio mixer has a output to the internal speaker. usually these can be controlled via a 'mixer' program, but the sound drivers have to know exactly what hardware is connected where on the outside of the core audio chip for all this to work sanely.
