Need a little help here,
built a machine p4p800 mobo, p4 3.2 chip, 1gig of ram. XP home OS. Update
BIOS. The p4p800 has a built in sound card correct? Hook up my Harman Kardon
speakers to it and I not getting stereo sound, music come out of only one
speaker. Checked speakers on another computer and I stereo sound. Any
suggestions would be appreciated.

Is there a balance slider in the mixer panel ? Check that it is centered,
so both sides get a signal.
It could be a bad jack on the motherboard, in which case returning it
to your retailer might be in order. You could try a set of headphones
plugged into lineout, to see if it is an issue with the plug on the
HK speakers. Another test you could do, is wire up a headphone jack
to the FPAUDIO 2x5 header on the motherboard, to see if the
audio signals themselves are working or not.
Some sound chip manufacturers have notoriously bad QA, but Analog
Devices (ADI) is not one of them.
Looking at a picture of the motherboard in the manual, some other
ideas come to mind. Before wiring up a headphone jack, make sure
the two jumpers on the FP_AUDIO header are in place. If one of
them is missing, that could kill an audio channel.
Another possibility, is something is shorting to the bottom of
the motherboard. For example, on an A7N8X, if an extra brass
standoff is placed in a certain location under the motherboard,
it kills the audio. To test for this, you could move the
motherboard outside the case, and do a "cardboard test". Put
some cardboard, or a large book, underneath the motherboard, while
you test the motherboard outside the case. Connect the other
components you need to test the audio and see if it works any
better. If the audio is still failing, it will then be a simple
matter to ship it back to the supplier. I like to test all
the components outside the case before assembling a PC, for this
very reason (to avoid wasting time assembling/disassembling
again).
