iPhone 5s, send "volume up" signal As many are aware, one can snap a photo using the "volume up" button and even the same button on the earbud volume controls.  I am trying to control the camera remotely and need more distance than the earbuds provide.  How can I generate the signal?  Are the specs available?  Is it a proprietary control or a simple on/off pulse on one of the three conductors through the stereo jack?  I tried a simple 1/8" stereo cable extension, but it doesn't work.
There is a proprietary micro-controller in the Applebuds, so you won't be able to simulate it. 

Maybe you could try a jack extension cord. (beware, you'll need a jack with 4 connectors).
