The audio ports (back and top) of my xps 8500 stopped working after my dog yanked at the output cable to my external speakers which was plugged into one of the six rear ports. Thinking the ports need replacing, I've opened the computer and tried to remove the audio port component from the motherboard, but it doesn't want to pull free. Does anyone know how to remove the unit? Can it be removed or is it integral to the motherboard? Thanks for your help.
