I have the same motherboard (I also got the same CPU and a similar case ) and never had this problem. I'm quite sure it's not about device driver, since mine worked "out of the box" (on Vista Business 32-bits and on Ubuntu x86-64). Don't know. If it's correctly plug and it doesn't work, guess it might be broken ?

Also, a note on the onboard sound; it isn't this good, I had a dedicated sound card on my last computer and even if that sound card was quite low-end, I noticed a difference in the quality of sound. Even if it's supose to be a good audio chip on the board. It still is... blah.

Is the sound driver installed, or the jack in the back is not working.

with some boards you can only output to one or the other. Make sure that you unplug the front jack and you might have to manually tell windows audio to output to the rear jack.

This could be off as I don't have the same board, but thought i'd throw it out there.

On some boards when the front panel audio jack is in use, it will cut the rear jack out of the loop, then when the front jack is no longer in use it will allow the signal through to the rear jack, if the front jack is not closing the circuit properly then no audio signal will reach the rear jack.

This type of setup usually instructs you to put jumper caps on certain pins on the front panel audio header when not in use, to allow the rear jack to work.

also may want to check the screw near the rear audio jack. Make sure it is not ground out, and if it is just get a rubber MB stand to put in the screws place.

Where would these jumper caps go? Directly onto the motherboard at some place? I notice there are four pins on my motherboard that are labeled "Speak", but nothing is attached to them. Rear speaker port does not work but front does. Also why doesn't the speaker jack seat all the way into the port. At least a 1/16" of the jack can still be seen.
