Headphone jack wiring problem
(1/4) > >>
blind_dado:
I have a female headphone jack on the front of my cabinet that has a wire with a male jack on the end that I plug into the computer inside of the cabinet.  The problem is that when I plug it in to the computer, all sound is diverted to the jack.  What I would like is to still hear the sound through the speakers until I plug in the headphones into the jack on the front of the cab. Does anyone have any ideas on how I could get this to work?
:dunno

Sounds like the jack in the pc would have to be wired differently.... kinda like having a normally open or normally closed switch. The jack in the pc is currently designed to be normally closed allowing the audio to run through the pc outputs, once you plug a headphone jack in there of any kind it opens that connection and diverts it all to the headphones. You would need the pc jack to remain closed with something plugged into it, but then have the one on the outside of the cab open when something is plugged into it.

Or something like that.... I'd have to poke at one a bit to describe it any better.

Yeah, I figured out what I would need conceptually, but I'm just wondering if anyone has confronted this issue and has some practical advice.  I know that Mountain has a headphone jack in his admin panel (see link below), but he doesn't explain how he wired it (but maybe he or someone else will have some ideas).

well wouldnt the headphone extension connection be open until you plug the actual headphones into it? The headphone extension shouldn't close the circuit

Not sure if this is something you'd want to do, but ripping the jack from the front of your pc and mounting it directly to your cab (and extending the wire obviously) should work. Shouldnt be more then a few screw holding the plastic piece into the case.

Other more complicated option probably exist (such has modifying your headphone cable extention with a normally closed female jack)

There is also the option of disabling front jack detection in your Soundcard driver configuration tool (so sound doesnt ever turn off when something is plugged in the jack), and adding a switch or button or whatever to turn off the sound coming out of your speakers, when you do decide to use your headphone.
