Internal speaker for Dell Precision T3600

Hi Everyone,

I was hoping to use an old dell internal speaker on T3600, and realized that the pin connector on motherboard (MB) is slightly different. The old speaker was taken from an Optiplex 745. On the 745 MB, the audio port is like one pin, space, three other pins, but on T3600 MB, the layout is three pins, space, one pin. The speaker has four cables, green,[space], black, white and red. I can plug in the speaker but it does not work properly.  

My question is if anyone knows the pinout on T3600 MB. I can then rearrange pin receptacles of the speaker to make the speaker work. 

Thank you,

DZ
