I ran lshw to see if I could get some more info on the box. One of the 
things it showed me was the Gateway model number of the machine. I'll 
put some of the output of lshw at the end of this post. Looking up the 
product on the Gateway support site turned up this interesting page:

http://support.gateway.com/s/CASES/shared/8011316/8011316mvr2.shtml

The internal speaker is not under the motherboard, but is located in the 
fan housing that directs air across the processor heat sink -- one of 
those big shiny fin things.

Another thing I got from that site was the user guide. It describes the 
functions of the five audio jacks, three on the back and two on the 
front of the box. The three on the back are, blue: Audio in/side speaker 
jack; green: Headphone/front speaker jack; red: Microphone jack. The two 
on the front are, green: Headphone jack; red: Microphone jack. The user 
guide explains that, "The five jacks can be used for more than one 
purpose. For example, the blue jack on the computer can be a stereo in 
jack or a stereo out jack." It also tells how to configure the five 
jacks, using the Windows control panel or the Realtek Sound Effect 
Manager, if it is installed.

So, now I need to find out if someone has created a Linux tool for 
configuring those jacks. They are part of the Intel D945GPB motherboard, 
so I would imagine someone might have worked something up for that.

Here are a few of the interesting things lshw showed me:
