Asus Essence STX II. Significant noise coming off studio monitors when connected.

[Ryan Brodrecht]

Hi,

I have an ASUS Essence STX II and every time I connect it to my JBL LSR305's I get noise, a lot of noise.

In a game like CSGO i get enough noise to literally drive me mad.
At first I thought it was a grounding issue so i replaced my PSU, nothing changed

oddly enough when i hit shift in minecraft the noise changes in pitch and tone slightly...

What i have tried:

Moving the soundcard to a different PCIe Lane.

Plugging the Monitors into different jacks (front IO, back headphone, back RCA, onboard back IO) all have varying levels of noise.

Tested speakers and sound card in an old HP gaming computer and the noise was significantly reduced

Untested:
EMI shield backplate on sound card

Specs:
Intel i7-5930k at 4ghz
Asus X99 Deluxe
G.Skill DDR4 4x4gb 3ghz
Nvidia Reference 980 ti
Asus Essence STX II
Corsair Obsidian 750D

Setup with GPU in top slot and Sound card in bottom slot


PLEASE HELP ME! IM LOSING MY MIND MAKE THE NOISE STOP!!!!!! HGAGASDFDSAFSDA

what does it sound like if running off onboard sound? or if you plug the speakers in to phone/mp3 player? Tried headphones on the asus sound card? Also make sure you dont have them plugged into the headphone amp output.

it sounds like static but not uniform static. sharp noises coming from it.

i have tried all plugs. headphones work fine.

I have the same crap and I do audio recording so I'm extra mad!! I've eliminated everything and even gotten new computers, speakers, audio interfaces and NOTHING WORKS!! I think it's my house.
