Front audio port static sound.

I just built a new computer and everything was fine when I started it. The sound was fine too. But the next day, I can hear static sound on my earphone. I already tried using different earphone but there's still a static sound. I tried the rear audio port and it was fine, but my earphone cord is not long enough to connect from the rear.

I tried moving the front audio wiring inside so it is not touching any wiring, it didn't work.

I read somewhere that I could "scratch" the front audio and usb circuitry, but I don't know what that means.
And also, making a "ground" solely for the front audio circuitry using an aluminum foil could work, but I'm not sure how to do that because the front audio and usb circuitry are one.

Check to make sure there is no breaks/cuts in the insulation for the wires going to the front panel connectors. Most likely need either need a new front panel or new case altogether.

It's the audio driver, sound blaster.

I uninstalled it and the hissing sound is gone, but now there's no sound.
The computer detects the headphone and the wave on the audio control is moving but there is no sound.
The rear is ok though.

Reinstalling will bring back the sound but also the hissing sound.
Speaker connected to front audio does not have hissing sound.

The thing that I want to work now is the sound without audio driver. But I have no idea how to fix this.

You can't get sound without installing sound driver. I believe you have an issue with the wiring going to the front panel. Either rma the front panel or buy a new case.

I tried to plug my old casing's front audio and the hissing sound is still present. Maybe it's the motherboard's on board sound card?

Also, I kinda force the motherboard a little on the casing, the screw is a little misaligned with the motherboard, could that damage the motherboard? It's because of the motherboard's rear cover(LED thing) the motherboard is a little misaligned.

You could have damaged the motherboard. Do you have the standoffs between the case and motherboard in the correct places? Build the motherboard outside of the case to make there is nothing shorted out.

I've put all 9 standoffs and 9 screws. The motherboard would have fit in perfectly without putting any force while screwing if I didn't have to put the LED cover which has a soft padding. I just had to put force so the padding will be pushed.

I just RMA both the motherboard and casing. Because the casing is making static buzzing sound even with using a working motherboard. While the motherboard makes the hissing sound with any working front audio port. And no sound at all without a driver.

I don't know if they could find any damage on the motherboard.
I wonder if Newegg replace an item even if they don't find any damage?
