Right that's a good sign,
first plug in one device at the front headphone slot and one at the rear, follow those steps again and do you see multiple bars stacked up to the right of the name such as "Headphone" or "Speakers? if so click the "Configure" button on the bottom right for each of the devices.
Like this:

After that click "Test" which speaker does it play from?
Do they all play via one of them?
Or does "Headphone" do the front jack and does "speakers" do the rear jacks?
If you would like a video demo to make it easier to understand just ask...
