Hello. You are going to have to go to the web site of the company that made your main board. look on your main board for the manufacture. take notes of the model number. go to support, and you will be able to download a manual on the mainboard. it will show you where everything plugs in. good luck !

My headphones will work but my desktop speakers will not why?


If your speakers work fine when plugged into the headphones socket on the front of the system, then there is no fault with them.
If the sound through the speakers is very low when plugged into the rear panel socket, that would suggest that you may be plugged into the line out socket rather than the speaker socket and that there is a mismatch of the impedence between the socket and speakers.
If you have three audio sockets on the rear panel, try the speakers in the second output socket (but not in the microphone socket) and see if it makes a difference.
You could try the same test using the headphones - do you still get good sound levels with the headphones when plugged in to the rear panel socket?
If neither the speakers nor headphones give good sound when plugged in to the rear panel, then you may have a problem with either the sound card if the sockets are on a separate PCI card, or with a poor connection on the cable to the socket header bracket from the motherboard pins for audio for integrated adapters.

I want to fit my headphone wire to the mic. wire


Check for 2 sockets. If your desktop is reasonably new, look for a socket with a Green ring around it or a socket within a green square. That is your headphones socket. Look likewise for a Rose colored one. That is your Microphone socket. At times you may also see the picture of an old fashioned Microphone and a headphone close to the respective sockets. If your computer is pretty old, get hold of a good torch light and look in the back. You may find a circle or a diamond shape with an arrow going in and an arrow going out which are the mic and audio out respectively. This type is pretty much rare now a days.

Mic In to pin 1; Gnd to pins 2 and 3; R Out to pin 5; Ret R to pin 6; L Out to pin 9, and Ret L to pin 10. Remove the jumpers on pins on the motherboard before placing thses wires.

Be sure that your headphone mic plug jack is plugged in to the mic jack (right-most jack) and not the second headphone jack. If so, check your sound setting in Control Panel and make sure the mic is enabled and the volume slider for it is up.
