Namco:
I got my headset jack working today. The solder pinouts were right, but my estimation on how the circuit worked was wrong. Bridging AGND with SPK does not "activate" or "route" the audio to the headphones, but rather inside the headphone jack with nothing plugged in, SW and SPK are closed. When you plug in a headset, it opens the connection between SW and SPK and sort of breaks the connection of the sound going to the speakers and instead it goes through the headset.

What I did was plug a naked 2.5mm plug into the jack which routes the sound to the headset solder points. I also wired SW and SPKR to a toggle switch, so when I toggle SW and SPKR closed, sound routes to the speakers instead of the headset. I use a 3.5 female to 2.5 male stepdown adapter to connect the headset to the standard 3.5mm jack that I use. I couldn't find the jacks that have the switch integrated, thus the need for the toggle.

Now that I'm thinking about it, I bet the mic is always on with this setup unless I unplug the headset. I'll have to test that.

Thanks to this post for helping me figure it out:

Here's the link to the correct jack that he mentions:
