plugging in headphones causes gamecube to reset

So I've been having a small issue with my headphone jack. I had this problem back with the Envision as well. Maybe one of you has experienced this before?

My switching headphone jack works properly and turns off the external speakers when I plug in my headphones BUT, it usually shorts out the system when I do so (system resets, and then works like normal).

I wired it using Mario's diagram. Thought I wired it right.....

stop shorting voltage and ground damnit

Whats wrong with my wiring. In the pics you can see how I wired everything. I have no idea whats wrong. I just followed Mario's diagram.

 

[ShockSlayer]

Try following your brain instead, yeah?

Use a multimeter to find out which pins on there are voltage, you probably weren't supposed to hook one of them up...

Well ground is touching L and R pins of the headphone jack as I put in the headphone plug.

So disconnecting ground eliminates this problem. But then I get what sounds like half of the audio through both ears. Reconnecting ground brings full audio. But plugging or unplugging the jack can cause the short.

No matter what, plugging in headphones causes pin 5 to touch 1,2 or 3,4. And obviously pin 5 is supposed to be ground. But lets say I wired it wrong, no matter how I swap around the wires of those 4 pins, ground will touch at least 2 of them. And I just checked, and ground CANNOT touch any of those 4 pins or the gamecube shorts out.

Is the amp mono or stereo?

Do you have a pinout of where you connected your wires on the amp?

You do the most amazing things Tchay baby, I don't even.

I dont send 5 directly to ground, I use a 1k resistor.

SS, it is stereo (you know me), Bruno, I'm ganna try the resistor and see what happens.

And Bruno, I'm guessing your circuit is mono?

EDIT:

So 1K was WAY too much. Eventually I got down to 1ohm exactly and it works! It prevents a ground shortage, but is not too strong to muffle that sound channel.

SO, either I'm a bafoon, or Mario's diagram is wrong and people have been using it all this time not noticing/caring.

One more question: anyone know the pinouts for a 2.2K trimmer potentiometer wheel? It has 5 pins. Haven't had much luck with it, and couldn't find anything online.

Have you tried playing with it with an ohmmeter?

Used ohms settings of my multimeter. But its confusing with this wheel. One of those pins needs to be grounded and then the other 4 pins are input and output of the L and R lines....

MARIO!!!!!!

I've always ignored the outer pins and only used the inner three.

 

[Ashen]

If you have this:

Place it with the pins pointing down and the 5-pin edge facing toward you. From left to right, the pins are:

1) Common (GND for audio use)
2) R1 Wiper (Out 1 for audio)
3) R2 Wiper (Out 2 for audio)
4) R2 End (In 2 for audio)
5) R1 End (In 1 for audio)

Mario's diagram isn't wrong.

Thanks Ashen!!! Thats the very same wheel I have. I'll try it out tonight.

And SS, maybe his diagram is right, but you can clearly see how I wired it in the pics, and it doesn't work properly. So I don't have an explanation for that, other than the original diagram being wrong.

Or maybe that diagram is designed for mono and I never realized it this whole time...

 

[ShockSlayer]

The diagram is a pinout, that has been tested and confirmed several thousand times by all sorts of electronics, it's not wrong, it's fact. It's not up to maybe, maybe not.
Also, if it was designed for mono(and it's not) then why would it specify L and R?
One other thing, not all headphone jacks are the same either, but yours looks just like one I've had before and it was the same as every other one.

I can clearly see that wires are going to places, that's about it. It's most likely the amp, or maybe you've got a wire going somewhere that you think is going to the right place but it actually isn't. Lots of things can look like ground, even on a multimeter.

There's no way for me to tell without being hands on, or you drawing up a pretty wiring diagram that you used, or showing me one of the amp as defined by someone else.

Fair enough, here ya go

Here is my setup. I tried wiring to the input pins on the amp, and it gives a BUZZING sound whenever the headphones aren't plugged in.

Obviously power and ground are wired up (just too lazy to show that). The blue lines going to the motherboard have 330ohm resistor each (it gave me a volume level that I liked)

Note that I reorganized my wiring so this is no longer the same as the pics in the first post. And yet the shorting continues to happen. The above wiring is the closest I could get to making this thing work.

Whoever feels like it, open photoshop and wire it the correct way for me using this blank template

Why would anyone use iluv amps anymore? Those $5 iPod amps are the best things around.
