What is this button that I press?

6 posts in this topic

Hello everyone

My headphones comes with a button on the wire that it claims will answer a call if I get phoned while wearing the headphones, but I would like to use that button for something else (e.g. turn it into a mute button or into a button that will let me change the speaker volume). I suspect that when I press that button, some kind of signal is sent to the computer (a mystery keypress, perhaps).

If I understand correctly, if I know what "key" that button is, then I can use IsPressed to sense it and modify its function. So, do any of you have any idea what that key might be, or how I can figure out what that key is? Would it be possible for me to get that answer without this becoming a keylogger thread?

I suppose one could also use AHK if that is more suitable for this task.

Thanks

Samuel

maybe start AU3Record, click the button a few times, then see if the resulting code is useful?

I suspect this button goes to a fourth connection thru the jack. Typical PC sound socket are stereo only and don't have provision for a 4th connection.

AFAIK in the traditional PC architecture only signals send to the former 8051 chip (now buried in the chipset) can identify keystrokes.

Is this a USB headset?


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I'm sure, no mobiles allow you to use USB headset :)

 

it claims will answer a call if I get phoned while wearing the headphones

 

Are you sure that your computer is able to detect thoose signals? If I'm right that usual inputs have 1 less "circle" than your headphone. That one circle which ur computer won't detect handles the signal to that answer button. This way I don't think that your computer detects that button, but it's my opinion :P

Thanks, but AU3Record doesn't record anything.

Nope... headphone jack.

Hmm, thanks.

So essentially I can't use this button on my PC at all. I plugged it into my smart phone and pressing the button in various ways does ilicit various responses from the phone. I suppose I can keep the headphones in the cupboard as a reserve, just in case the one that has volume controls breaks.
