SB-Live Value external headphone jack

[Skidmark]

I'm trying to add a headphone jack to the front of my case. My SB Live Value aparently has the ability to hook-up a live-drive to give me the added functionality, but I don't want to spend the money. All I want is to connect a 3-pin jumper to the live from a headphone jack, but I don't know which pins to connect to, and I don't much feel like messing with it and frying anything. It mentions which pins do what in the help menu, but I have no idea which pin is number 1. Can someone point me in the right direction? I've been scouring the net with no success.

hrmm... maybe I shoulda tried that Pin one should be labeled on the board.

BTW, where did you get the info for the pin outs?

I just use a Y-splitter for the headphones to run off the main speaker port.

i'm wondering if there are three pins you can hook up to because w/ a live drive, when you plug in the headphones, it mutes the speakers... which is what I want. But I'm getting rid of my live drive for cash, and will make a makeshift switch possibly... or try messin w/ that internal connector.

Headphones usually come with volume control on the wire, and speakers are easier to turn off than plugging in head phones.

don't really like that.

Not all headphones have volume knobs, ie, my MDR-V600's.. not to mention i really don't like them.

And turning off speakers (or, in my case, cutting the volume down) is too easy

I installed the drivers off the net and the LiveWare 3.0 and in the start-menu there is a user guide that lists all the pin-outs, but no pictures:

Great, groovy, wonderful. Now which pin would be stereo-left, stereo right, and ground? If I had a Live Drive I could just look to see which pins run to the headphone jack. I would kinda assume I would use the general purpose output #0, 1 or 2...but who knows... 0,1,ground?

And if pin 1 is labled, do the pins run 1-20, 2-40 or 1,2...39,40 up and down? I'm leaning towards up and down since 29,30 are KEY which I (another) assume that means the 2 pins that aren't there. the block looks like :::::::::::::: ::::: and they're perfect sized for adding pins and I've even heard you could plug an IDE cable to it...

I tried using a Y splitter, but I would love the added functionality of disabling the speakers and enabling the headphone when it's plugged in (which is also an assumption).
