Solution to GPU coil whine crosstalk to audio jack?

[menyus420]

Hi

 

My GPU coil whine is audible trough the 3.5mm audio jack when there is high load on the GPU, and got worse over time. Does someone know any solution to this? Is this because a super noisy graphics card or bad audio circuit design on the motherboard? Would a discrete sound card solve the issue?

 

Thanks,

It's because the graphics card is emitting EMI and it's interfering with the audio signal. You could get a sound card, but you would want to make sure the whole thing has a shield on it that's connected to ground. An external DAC might be a better solution.

Usually with good sound cards, they use a multilayer pcb, and the outer layers are used as a shield, with all the traces hidden with the inner layers. That generally should do it.

 

The ultimate solution is fiber optics. So, using toslink to an external dac. Then there is no electrical path from the pc to the dac anymore.

I highly double the coil whine would come across a USB data connection so I'd suggest an external audio interface for the same reason the other responses suggest a sound card or DAC. The reason I tent to suggest an interface over a standalone DAC or soundcard is that of value for money, you get far more functionality for (often) less money. The ability to use real XLR microphones is not to be laughed at, your discord pals will love you for it (plus you can still use it just as a headphone amp or speaker controller if you don't need that functionality)

Even Soundcards via USB can get those whines. Often than it is through groundloops somewhere between your PC and external stuff. Often a cheap DI Box does the job. There are different sizes for different jobs.

For you for example, something like that can help:

Thanks for the answers! The noise filter jack extension would be an okay price, but i wouldnt want want to shill out more for the solution.

 

But the other interesting thing is, i plugged the headphones into the front panel jack, and i can not hear the noise at all. Strange. It is bit inconvinient and a bit ugly but i think i will use that.

Anyway you could record this and post it here?

So i tried to record it but the nvidia shadowplay record does not capture it, i think thats because the noise sits on the analog side of the back jack connection (makes sense to me).
Tomorrow i will try to plug a speaker to it and record with my phone.

Again, this whine can be solved through use of an external USB audio device, though some have been known to continue to whine this is likely from interference over the USB power rails in which case it is very possible to externally power the device and utilise only the data lines to connect to the PC through a little cable modification. Of course all of these are just bandaids and in reality replacing the GPU is the obvious answer.
