  1. hi all, I have a P4SD-LA motherboard and the sounds not working.. i installed Realtek AC'97 after reformatting and its not putting out sound.

    do i need to set some jumpers or sometin? also i moved the motherboard from its old Compaq Presario case to a TT Swing case.. so the front panel (earphone jack, mic in, USBx2, firewire) is not plugged in nemore..

    could this be cuz the slots for the front panel are left wide open? do i have to put some jumpers on them?

    yes, you need the jumpers or else your card will not be usable.

    somewhere on the surface of your motherboard, there exists a jumper block for the FP audio hookups. if you disconnect the headers to the front panel and want to use the ports on the rear of the board, numerous jumpers need to be affixed to said block to complete the circuits to the back panel. your motherboard's manual should display where the jumpers need to go. without these jumpers, your soundcard's circuitry will not be electrically connnected to the jacks on the back of the box.

    ahh just as i thot... anyway i bought this computer OEM from futureshop.. so i dont get a manual... I found an "Oxford" manual for this motherboard, however, it does not tell where to put the jumpers... :(

    do u know where i could find a manual for this?
    does anyone one know plz?

    is there anything printed on the motherboard's pcb near the jumper block? finding the block shouldn't be too hard...

    yea i know where the conectors go.. the problem was that the wires the case came with, doesnt fit in the mobo slot for the FP sound .. so i jus basically took the wire from the old case and did a little modding.. i connected the coresponding wires from the old wire to the wire the case came with and connected it that way... (the old wire was the only one that would fit in the FP audio slot in the mobo :S )

    neway thanks for confirming about the jumpers

    beware of short circuts... i often coem across machines where someone had a short in thier FP wiring. in all cases there were numerous melted wires.

    what do u mean by "had a short" like. they missed to connect one wire?
    what are the odds of shorting my wires? ur starting to scare me.. maybe i should jus unplug them =S

    I have couple jumpers left from my old mobo (i took them out when i was placing my FP wiring) can i used those on any mobo?

    the P4SD i have only has 5 slots for the audio.. and 3 for mic.. but theyre in a totally different section on the mobo.. i should take some pictures to show u what i mean..

    if you're careful and assume nothing you'll do fine. it is the people who assume without checking who short thier wires.
