Only one PC Speaker working

kaaloo

Ill be brief:

Speakers are brand new and tested and both are working 100%

I have a pc that has been custom made (by me) and when I connect the speakers only one works.

Can someone tell me where I have gone wrong? I just cannot work it out. I suspect it has something to do with the FRONT PANEL AUDIO connections but I cant sort it out!

The pins for front audio are a bit funny on motherboards, the jumpers are closed on front mobo connectors because they lead to back ports, if you remove one of the jumpers it cuts the circuit. same as when you connect a front port the circuit is cut too the back.

thanks - i still dont know how to sort the prob!! Any ideas on what I should do? What wire actually controls the speaker connection from the mobo?

I have noticed that if I remove the Front Panel connector jumper, neither speaker works but when i fit the jumper, only the left one works

Each speaker need a signal & return so their shound be two pins for each speaker, & a jumper on each connection.
Thier should be a label L & R for left & Right, and G for ground/return.
You should have two jumpers next to each other on the front jumper connectors to connect the mobo with Left & right signals.
