I don't have that one, but you're free to edit my diagram if you want.

@yves1984 You'd probably be better buying an assortment of resistors, since you may need other values and they're handy to have. Those should do the trick, but 0.5w resistors are larger and easier to work with, and will be a little bit more robust.
You'll find something like
this much more useful.

that will be a good idea, but they don't have a 47kOhm.
Did u wiring some resistor in serie to have 47kOhm?

@yves1984 You could, but have a look for other assorted packs. You'll find one with the values you need.

Can someone explain what "Switch" is? And also, why isn't the speakers positive connected to "Speaker +"?

@helder mentioned in another thread that the "switch" pad is treated as ground if not using the original DMG headphone jack. I have my third party jack hooked up as shown in the diagram and it works as intended.
no headphones plugged in - audio goes into the jack and out to the speaker
headphones plugged in - audio goes into the jack and gets directed to the headphones instead of the speaker

But with your current setup, only 1 channel gets played, left or right.

Stereo always goes to the headphone but since you have 1 MONO speaker you get one channel since it is Mono. What is wrong with this setup? I don't understand what you're trying to say with that post.

Yes, plugging in headphones gives stereo, but the speaker is only playing left or right, not a mix of both. So something playing only on the left/right side would not be heard with the speakers.
