IEC958 is generally the digital audio feature (if your board has one).

Many onboard audio devices are really badly designed and have insufficient
power isolation, which means you get lots of noise.

If you were using the digital output it should elliminate that of course,
assuming you have one.

I have in the past encountered onboard sounds that clearly let you hear
the HD accesses, the network packets, the mouse cursor moving, etc.
It was quite awful.  Higher end boards tend to have much better onboard
audio designs, although a good add in card will generally be much better,
although if you could use the digital output instead it shouldn't matter.
That of course means the other end needs a digital audio input.
