Question Constant Static Noise Sound Coming From Speakesrs

[OfficialKHAN]

Hi friends,

I've recently built a new computer, see parts here: https://uk.pcpartpicker.com/list/xQkby4

The speakers are plugged into the rear aux cable of the desktop and i can hear a constant static ,crackling sound coming from the speakers. If i move the mouse i can hear a higher frequency sound as i move it.

Having searched around ive tried the following:

Problem:
- Plugged speakers into rear aux cable of the desktop (Bad, noise)

Troubleshooting attempts:

1. speakers into laptop (Good, no noise)
- This suggests to me the speakers on their own are working?

2. earphones into rear aux cable of the deskptop (Good, no noise)
- This suggets to me that the rear aux input is working?

3. unplugged the entire machine so now its only the PSU cable and speakers plugged into the desktop (Bad, noise).

4. I purchased a ground loop noise isolator and used that in between the speakers and my desktop rear aux cable (Bad, noise)

Drivers:

I have the audio driver installed which can be found on the motherboard website https://www.msi.com/Motherboard/support/MEG-Z490-UNIFY#down-driver&Win10 64 - i hear the noises even before windows boots.


Having tried these im really struggling to understand this problem, if you have any potential solutions that can help me isolate or fix this issue, please let me know.


- I live in the UK and from what i read all plugs are grounded as we have a 3 prong system

By auxiliary port, I'm assuming you plugged your headset into the red port? If so, then make sure you're on the latest BIOS update for your motherboard. You might want to state the make and model of the speakers. TO me, it seems like you might have a grounding problem in your crib or at the very least the power outlet in the room where the desktop is located.

You might want to see if relocating the desktop to another outlet changes you audio experience.

After doing some more testing i found the following.

1. I took out my GPU and turned on the computer with just the PSU and speakers in. I could no longer hear the static/crackling/poping sound. The only sound that remained was white noise.
2. I put the GPU back in in the, static/crackling/poping came back
3. I tried a different GPU the static/crackling/poping came back
4. I tried a lower PCI slot and static/crackling/poping came back.

So it looks like i am receiving this interferance because i have a GPU installed in my computer.

I want to know your opinoin, do these tests point towards it being an issue with the motherboard?

Can you please move this thread to either the GPU or motherboard section?
