The front headphone jack split open (front bay audio panel) and disintegrated into 6 pieces. I have a spare 6.5 mm jack as well as another 3.5 mm one, but it only has 2 contacts instead of the four on the broken one.

 

I can work out the two wires that correspond with the two contacts on the new jack, the left and right. But I don't know what to do with the two leads left over (headphone detection and sense or whatever) these two seem to be responsible for detecting the presence of a plug, so could I just solder a switch across the two wires so that I can just toggle it manually?

 

There is a pair of audio connectors on the case itself which I can't connect to the mobo, so if it is not possible to use a 2 contact jack, then I have the option to desolder the old microphone jack on the case itself (which I don't use)

 

I hope this all makes sense...

 

~7 year old Gigabyte full tower

MSI 970 Gaming motherboard

Aerocool Strike X X-1000 front panel 

 

spare parts:

6.5 mm 2 contact jack (with 3.5 mm adapter)

3.5 mm 2 contact jack

potentially a 3.5 mm 4 contact jack if I desolder the one on the case.

various wires and switches

 

thanks

Yes you can use that 2 contact jack and switches but it will be more convenient the 3rd option to desolder the mic jack if you are sure it is similar to the headphones jack.

Don't forget to short the contacts 1-2 and 3-4 after desolder the jack as normally they are shorted when unplugged. Otherwise your Mobo will think the mic is plugged in.

Besides the left and right audio channels, there's a ground and a pair connected to the board mounted jack to sense or switch the headphone circuits.

Ok, thanks. I thought about it and I'll probably just swap mic wires with the headphone wires on the cable as both jacks are identical.
