ah problem, i can not see where it states the make or model of the motherboard., there are some white stickers by the memory slots, with the word intel under but then the sticker is over the top. and i think i now know why i have no audio, when i was fiddling the other day, i must have removed the wires from the front audio jacks, as they are not connected. i have found the hub lablled audio config, and the wires are lablled, mic-power, mic-in and ground on one lot and the other has l-out, r-out, l-ret, r-ret and ground, and i am totally clueless as to how to wire them up. i also have another set of wires lablled vcc, +d, -d and ground, two sets one with 1 precedding the labels and the other labelled two. this may explain why my audio is not working.
