Front panel sound and USB

Posted on 2005-05-12

I am having trouble getting my front panel sound and usb working.  I never can get them to work when I build PC's.  The USB connectors from the case are a single 5-pin bar.  Right now I have the writing facing up, and the USB doesnt work, so I take it that it needs to be facing down.  The sound is another story.  The motherboard (ASUS A8N-SLI Deluxe) shows a diagram for connecting the sound but the case (Thermaltake Tsunami V3000) has different wording.  For example, the case has "Ear R", "Ear L", "MicVCC", etc, while the motherboard has "Bline out R", "Bline out L" etc.  I have the "Right return" connected to the Bline and the "Ear" ones connected to the "Line Out" ones, but they dont' work.  Can anyone help?

    If you have tried all combinations of putting the wires around different ways I would assume the case usb/audio cables or motherboard headers for the connection is screwed.

    Cheap way of finding out would be to find some addon usb's that usually slot into the back of your case, where the pci slots are, but is not pci, its just cables again and plug them in, you will be able to determine fairly sure if its the cables then or the motherboard.

    First of all, lets talk about your USB cable, it really does not matter which way the writing is facing, what matter is the words that's printed on it.  All front USB connector have 4 connection pins, they are +5V, - , + , GND (Ground), if your case's front USB connector pins is seperated into each individual pins, then you must connect them in this order, if you don't do that, the wire will heat up and may cause perminate damage to your motherboard and case.  In your situation, your mother board have 3 onboard USB Connection pins set (6 USB Connections total) right under your motherboard's battery, they look something like this  

    : : : : '

    and this is the pin's layout seperated by " , "

    +5 , - , + , GND , No Connection
    +5 , - , + , GND

    So just match the pins with the words on the connector, and you should be fine, if by any chance your connector does not say anything, then the +5 is usually a Red Wire, and GND is a Black Wire.  

    After you conncted the USB Pins and start windows, your USB Ports should be ready to use, if not, go into your bios setting and enable your onboard USB Ports then try again.  ( Under Advance / Onboard Device Configuration / USB Configuration )

    Second, I'm not sure how you're connection the audio pins, but from my understanding, you're connecting it wrong, your audio pins looks something like this (the pin set right behind the audio jack)

    ' '
    ' '
    ' '
    ' '

    Now, I will asume you have a 5 connection pin front audio cable, they are Ear R, Ear L , MicVCC,  +5V , GND  , and here's how you connect the pins , ' measn no connection.

    ' , Ear L
      , '
    ' , Ear R
    +5V , MicVCC
    GND , '

    When you're doing this, make sure that there is no Jumper on any of these pins, some motherboard will have jumpers on the audio pin set because you can only choose between the back audio out or the front audio out.  so basically, besides your front audio connectors cables, there should be nothing else on the audio pin set.  

    I believe this should solve your problem
