Static noise

[Divisiondoorway1]

So I just build a new computer using these parts https://pcpartpicker.com/list/X4qK8Y and I have updated almost all of the drivers even flashed bios. But when I plug my headphones in (shp9500s) to the back port for speakers and headphones I get static noise. I have speakers that I use as well (creative inspire t10s) when I use the same cord to plug those in the same port I do not hear the static noise. I have tested my headphones to make sure its not just the them as well, I used a pair of Skull candy earbuds and plugged those into the back port and the noise was even louder. I tested my front audio port with these skull candy earbuds and it gets less static noise but its still there, but my SHP9500s do not as much noise in the front port (all most  not noticeable). I have reinstalled my audio drivers multiple times already and nothing seems to change this problem the only way I can fix this is too plug the headphones into the LINE IN port on the back of the motherboard but its not as loud as the main port on the motherboard and when I restart the computer I need to plug it into the main back port then back to the LINE IN port which is a chore. Is there anything I can do to fix this issue?

Is your machine properly grounded at the outlet?  And why are you plugging your headphones in to the LINE IN port?  Plug them in to the LINE OUT port and see what happens.  The LINE IN port is used for MICROPHONES.

Yes it is grounded at the outlet and the reason I would plug it into line in is because it gets rid of the static for some reason I do not know. the line out port that is the standard on the motherboard is the one that gives the static. when I use the line in port I plug it in and realtek pops up and asks if its headphones or a mic or like different types of speakers I select headphones and it doesnt give me static but gives me sound. I dont understand why this is happening

The motherboard has reviews of other people stating this problem as well so it might just be the board but it would be nice if there was some sort of fix for this. The problem might be that the board comes with a removable amp that you can replace and the amp they may put in these boards is just junk

Edit: when I use 100% of my cpu through a stress test it doesnt do it but when Im not stress testing it does make the static electrical noise through my headphones

@Divisiondoorway1 : There's some basic things to try. Disconnect the front panel audio connector and try again. Noise picked up by this cable (which in essence is a large antenna inside a noisy PC) can backfeed to the audio circuits and appear on the rear connector. Try keeping the 4/8 pin 12V CPU power cables and any PCI-e video card power cables away from the rest of the motherboard's power cables and not tie them all together. The CPU/GPU power cables will have buck regulator switching noise on them which can capacitively couple to any cables next to them, some of those other cables are powering the audio circuits. Keep noisy cards away from the audio circuits on the motherboard, for example it's a bad idea to have your geforce dangle right above the audio circuits on the motherboard, in such a case you might try moving the card to another slot, if available.

 

If nothing helps then I guess it comes down to board design, swapping out the opamp is not going to help much in that case.
