Audio annoyance..

[Wraith]

OK all you Audiophiles and budding driver nuts, solve this?

My System consists of the following:

MoBo: Gigabyte GA-78LMT-USB3
CPU: AMD FX-4100 (OC'd 4.01Ghz)
RAM: 8 GB Dominator Platinum (1333Mhz/Motherboard limited)
RAM: 8 GB XMS3 (1333Mhz)
GPU: Asus GTX 750 Ti OC
SSD: Crucial V4 64GB
SSD: Corsair LX 256GB
HDD: WD Black 500GB
PSU: Corsair CS650M

To the matter at hand, after rebuilding my system, once I had the OS installed I started with the mainboard drivers with no issues, all is great and perfect, but once I'd installed the latest nVidia 340.52 Drivers all audio is now affected by what can only be described as quiet morse code/scratchy white noise in the background, whether it's moving the mouse or anything video related this annoying noise follows.. any suggestions would be grand.

Try going into Device Manager -> System Devices and disable High Definition Audio Controller. Just disable one at a time and see if any of them stops that noise.

No dice still annoying as hell.

EDIT: Temp fix, I'm using front panel jacks with no interference so far.

What OS are you using Wraith because if you put the latest drivers in from gigabyte sometimes windows will download a generic driver that mucks it all up so for now try turning off windows update and then reinstall the latest audio drivers for your board from gigabyte and see how that goes

 

[Wraith]

Windows 7 Ultimate 64, fully updated and the latest Gigabyte board drivers, going to try the newest realtek drivers later, but to be honest I think this is frequency related interference, it seems to get worse the more I ask from the GPU.

Since moving to the front panel audio I can't hear it.

Does the Nvidia driver have an audio option for HDMI when installing? Can you reinstall and do a custom install and not include these?

Tried it fella, this is interference on a hardware level, I guessing the lack of shielding on the rear audio I/O is the cause.

Glad you worked it out Wraith

Glad you worked it out Wraith

I don't think it's fixed though.

Did this only start once you put the GPu drivers on? Is it only when your GPU is stressed?

I've had it before, but put a lot of it down to coil whine, is it really very loud? Does it come through the headphones/speakers or is it coming directly from the case?

When I had the Gigabyte GA-78LMT-USB3, i did not have this problem with i/o 3.5mm jacks.

It sounds like other components are intefearing with the audio traces on the motherboard. some of the computers in my school have very crap motherboards, and do the same and its very noticable. Moving mouse, or stressing the cpu will make the noise much louder and change the pitch. glad to know hd audio port hasnt got any problems.

No I didn't say it was fixed just that he worked it out TBH I'm not really sure how to fix it or if it's even possible to without changing out the board which is gonna suck big time, maybe a way around it is a cheap Asus soundcard?

Yes only started after the GPU drivers were installed, Only happens when I do something visual the more I do the louder it gets, hovering over links or scrolling causes a binary/morse code sound (very feint) but give it some youtube or games and it's quite noticeable, no noise from the case though it's only though the headset.

I think I've nailed it down anyway, I think it's due to the location of the PCI 6 pin connector on the card being at the I/O end of the card and not the far side like usual, so the power chokes are interfering with the audio ports on the motherboard.

Can you find a ferrite ring to put around the power cord?
