I cannot be sure if I have a real one or a fake. Music sounds ok when it's not in TV out mode, but some parts are missing on some tracks. I'm guessing I'm hearing left or right channel only on both sides - but I'd need to find a file to test that with to be sure.
The one I got looks exactly like the one at the top of this thread. It came without the headphones. It even had the cable tie wrapped in the same way.

Argh! I've just done a left/right channel test... and in normal and in TV out mode the left and right channels are separate and correct. It turns out the AD-54 I have has a slightly dodgy connection.

The test I used is here - http://www.wooferbasstest.com/left-a...d-effects.html if that's any use to anyone.

So after taking a complete wrong turning... apologies... back to what t1mman was saying...

There is no response at all from the Nokia buttons. I've even made sure I'm wiggling the wires about while I do it with both the device switched to the in position and the off position. As I'm still not convinced though I wouldn't mind lgkahn's input on it - Do the buttons work in any way for you on the AD-54?

We know at this stage then that the Samsung and the Nokia both use the same channel (ring2) (my rusty electrical knowledge tells me that it is not possible to use ground?). However the SGS is either incapable of seeing the Nokia signals, or is not looking for them so ignores them... I think that's the summary of where things are.

Going forward from here I think there's no point in trying a iPod pushbutton thing - so unless someone has a different opinion I won't bother getting one off eBay.

It would be interesting for someone who knows more about the phone itself to let us know if it's even conceivable to try to see if the phone is seeing a signal, because if it is seeing a signal then perhaps it could be taught to respond to it? I'm way out of my depth there.

Other than that though, it seems to me that the Nokia device serves no purpose, and the only way to pause/play music is to use an app that pauses/plays when the headphones are disconnected.

hi, i guess that this approach is dead isnt?

I want to know the same..
