Hi,
I have a Xonar DX and, some reason it makes a high pitched noise, it's low in volume but once I hear it I cant unhear it, it drives me crazy because of how subtle it is. (it becomes more obvious if i use my IEM)
However, it seems that it only makes on my PC, since I asked friend, who seems to be pretty sensitive to these kind o noises to test in his PC.
I have tried chaging PSU, Graphics card, RAM,sound card's power cable, power socket, turning off everything in the room.
The only things I have not tried are chaging processor, motherboard, HDD, case.
 
My motherboards built-in sound card doesn't make this noise.
I have the feeling that it's most likely because of the motherboard, however, I want to wait a bit more before upgrading.
 
Do you guys have any solutions I may try?
 
 
Specs:
Motherboard: Sabertooth 55i
Processor: i5 750 @3.8
RAM: 8GB DDR3 1600Mhz
PSU: Corsair TX850M
Graphics card: Gigabyte GTX760
Case: Nox VX

Move the Xonar DX to the PCI-E slot farthest from the graphics card.
Did you disable the motherboard's on-board audio, in the BIOS?
Try installing the third party drivers "Unified Xonar Drivers".

1- I removed my graphics card, changed pci-e slot and I can still hear it.
2- Yes, before anyone ask, I did that, turn off C-states and other power saving features, tried reseting the BIOS and still nothing.
3- Been using them since day 1.
 
Also, I would like to say that this is not a software problem, believe me, I've tried different OSes and drivers (both official and modded, old and new)

You do have the 4-pin power connection hooked to the DX?
 
If it's a problem with the Xonar DX card itself, you could get a Xonar DG ($26 - $10 mail in rebate, Amazon), it's a cheap way to see it's if maybe the Xonar DX is defective. As you say on-board does not have the same problem.

Does the noise depend on system activity, or is it constant ?
 
Are you using the front panel headphone jack on the PC ?

Constant, I've tried with both GPU and CPU on full load and it doesn't change at all.
It's directly connected to the card.

I'm in europe and it's quite a bit more expensive here.
I don't really want to buy sound card to return later.
