I recently had to change the motherboard out of an emachines T1840, now the front panel connection don’t match up. I managed to find the left and right audio for the headphone jack (black and red skinny pair) but there is a thinck black wire leftover, also the sound is fairly weak coming out of the fron connection. The mic jack consists of a red thin wire and a black thin wire and a third black thick wire. I’m totally lost on this one any help you can provide would be appreciated. Thanks
