Why is everybody complaining? Gigabyte does not seem to pretend that this MB is delivering Hifi audio. (it would then be called GA-Z170N-HIFI, no?)
It says there right in the product name: GA-Z170N-
WIFI. It should be pretty clear from the product name that this MB is only capable of delivering audio in
wishy-washy
fidelity...

Also, the LED's cannot sit in or underneath a guard track - which would be made of copper. And to my knowledge, the light from a tiny LED does not shine through a copper trace.
Obviously, the LED's sit somewhere (embedded?) in the PCB substrate, but why are some people here so certain about them sitting in the audio area? By all means and purposes they would in all likelihood sit outside the PCB area dedicated to the analog audio circuitry.
And since the analog audio circuitry has to be shielded from the rest of the MB electronics and (high-speed) digital signal lines anyhow (assuming that GB is somewhat serious with its claims about audio quality), adding two or three PWM-controlled LEDs somewhere outside of the analog audio area should not make much of a difference... i guess...
