Need HDMI as going to be doing REW tuning soon.
Lifting PC ground worked. Would grounding the chassis to a nearby radiator be safe? I Might even build the PC into an MDF 4U cabinet with vented panel that I aleady have.

I couldn't tell you. Get an electrician in who knows what they are doing.
Glad you got rid of the hum.
Those type of products reduce audio quality. They are basically a filter.
This would probably work but im running a 7.1.4 setup

Nvidia need to work on the EMI as its off the charts!
The sad thing is there is no soundcard with a HDMI out that'll bitstream dolby atmos and DTSX as that would solve the problem too.
I wish RME would release a hometheatre / gaming soundcard with decoding capabilities. The sound quality is so much better too.
That or a software decoder for dolby Atmos or DTS X. Maybe powerDVD will add it one day so I can get rid of this prepro and get a professional soundcard again.
Sounds like they need to shield the soundcard part for the graphics card more as its too close to the GPU chip itself.

HDMI over CATx/HDBT was the only type of "filter" I would entertain and it's dead in the water it seems. HDMI over fiber is the only other way since the cables aren't shielded, but it's not cheap and minimum length cable seems to be 20m @ £170+, that's £340+ for two + ~30m of fragile cable to "hide" - no thanks, unless you spend ~£700-750 for the transmitter/receiver/multimode cables combo that is.
I want to avoid putting anything that would mess with the signal between AVR and power amp (DI box etc), already not looking forward to adding a minidsp soon for eq/hpf.
I did some reading about ground loops, thinking it may be the additional length of mains cable between PC and outlet vs outlet and amp causing a difference in potential, I decided to try the PC sat right beside the AVR cabinet, again plugged into the same outlet, with a shorter mains and connected to the AVR with just a 1m HDMI; the noise was insane!
With the PSU on/PC off there was a constant whistling, powering up sounding like a fax machine on crack with added pops, farts and fuzz. Tried again using the lifted mains cable on the PC but that just changed the frequency not severity.
Since my only other option appears to be running the PC ground lifted, back at the other side of the room and I will most likely be re-building it into a wooden box; before doing so I'll test with the GPU and its CLC removed to see if it's clean from IGPU alone.

I feel your pain.
I wish I knew more about groundloops and how to prevent them. I have a limited understanding but it half makes me want to start a physics degree!
I have a degree in music production and after working in so many studios and seeing the amount of equipment with power ground lifts it looks like there is no easy fix.
Putting electronic items near each other will also cause more EMI. If I have my Guitar preamp on top of my Guitar poweramp I also get hum.
Shame you can’t get balanced hdmi cables! (Joke)
Nvidia should really work on this or marantz should work on their hdmi inputs.
It all boils down to nvidia cards having their components so close together.
If you use the nvidia output as the video output and the inbuilt igpu for Audio you still have the same issue and will probably lose hdcp 2.2 compliance too.
Lifting the power is the only real way to do it as far as I’m aware.
Hopefully some physics professor will chip in and give us a safer solution.

@GibsonRed I registered on these forums to thank you so much for detailing all that you went through with this Nvidia noise problem with active speakers.
I too am experiencing something very similar and have been extremely perplexed and frustrated trawling through lots of online forums trying to figure out why it was happening and what solutions were being suggested.
I knew that it was the video card under load that was causing the problem, but after faffing around changing cables, power sources, ferrite chokes etc nothing I did made any difference. lockjaw333 suggested a powered USB hub and that has helped reduce the noise a little but definitely not eliminated it.
I will be trying the ground lift method and see if that helps. I've recently come across a post from someone called gunslingor on Toms Guide with thread entitled "High pitched static sound from speakers"...in this thread, after lots of trial and error he eventually found that EB Tech HumX helped him to significantly reduce the noise. Just thought I'd reference this in case it helps anyone stumbling across this thread. Some people are also saying that AudioQuest Jitterbug could help too. Along with Behringer HD400 Hum Destroyer. Hopefully some combination of these will get rid of the accursed coil whine.
Thanks to all who have positively contributed to the thread.

You’re welcome.
I still have this problem even though I’m now running a 8700k.
Looks like nvidia would have to step up to fix this issue.
How nvidia thinks these noises are acceptable are beyond me.
Surely someone would have tested this?!?
I mentioned the humX and behringer hum destroyer earlier in the thread.
Only problem is I’m based in the UK and they don’t have a humX version for my country.
I just lift the ground on the PC. I’ve not been shocked yet.
Maybe nvidia should rebrand their gaming cards from GeForce to HumSource! The ‘nvidia humsource? I’ve found it’ edition.

I get the impression that Nvidia don't really concern themselves with the "noisy interference" to sensitive audio equipment. It seems their primary aim is optimising their graphics card purely for the visual display. Perhaps understandable but, like you, I just don't get how they think this is "acceptable". Perhaps the powers that be at Nvidia don't use their own cards in audio sensitive/critical environments either.
A bit of good news is that we can now get hold of EBTech Hum X now in the UK https://www.amazon.co.uk/EBTECH-HE-2-Ebtech-Hum-Eliminator/dp/B0002E4YH4/ref=sr_1_fkmr1_1?ie=UTF8&qid=1525537627&sr=8-1-fkmr1&keywords=hum+x+ground+isolator
I'm holding off the ground lift on the PC until I've tried the Jitterbug and Behringer HD400 hum destroyer (which I think works just like the EBTech HumX.) I've ordered both but there seems to be a bit of delay on the Behringer. Also going to try the Ex-Pro® AV Link Ground Loop Isolator / Elminator to see how well it works.
The noise is only really a problem when I play the occasional game, it just affects the "near field speakers" really badly, but for normal purposes and home studio use it isn't really an issue for me because the card is not under load.
When I was scouring through the online threads/websites there seemed to be sooo much misinformation out there, people were trying all sorts of things to find out what was causing the problem, sometimes going to extreme lengths and virtually rebuilding their PCs. All because of what you rightly call "Nvidia Humsource".
I'm not sure if AMD graphics cards have the same problem, but at least we know what's causing it in our setups.

Just to add to the appreciation for this thread and the detailed steps in trying to figure it out. Same thing here, GTX 980Ti with HDMI out to a Pioneer VSX-1021 which worked just fine in desktop situations (e.g. Spotify) but created an almighty banging/humming through HDMI into the subwoofer when put under any stress at all - Ghost Recon Wildlands being the worst offender in my limited testing.
Anyway, to summarise - picked up a cheap ground lift from Amazon (3-pin to 2-pin) for the PC power which solved things instantly, and then replaced that with the EBTech Hum X which performed the same job, albeit safely.
Thanks again... after diligently setting up 7 speakers and a sub, everything working beautifully over HDMI with a PS4 and an Xbox One and then the PC freaking out like it did in the same environment, this thread was the first thread on the topic that made any sense. :)

I was having an issue with a ground loop. Similar setup.
PC with 2 1080ti SLI
Marantz preamp (have used balances xlr and rca)
Emotiva 2 channel amp
Emotiva 7 channel amp
Powered sub.
9 speakers
Projector
I got a loop when the sub was hooked up.
I was able to kill it by using an rca to optical converter to a fibre optic cable and an optical to rca converter. It breaks the electric connection.
I also get a ground loop with my PC. I can kill this using a NVidia Shield and Gamestream. Though this has some limitations.
I just discovered that there are now Fibre optic hdmi cables. I expect they will end the ground loop by breaking the electrical connection. I’m going to get one and try it but my main home is under revocation and most of the theatre stuff is packed up. I’ll probably be able to test it out in February after I’m moved back in and settled. You might want to give that a try.

Let us know if the optical hdmi cables fix it.
I’m still using the power ground lift switch on my PC as it works a treat.
I upgraded my 980ti to a 2080ti too and it still makes the noise.
If only someone would bring a sound card with an hdmi output and Dolby Atmos and DTS:X decoding capabilities.
Would be nice if someone from Nvidia would tell us WTF is really happening, its not right having to cut the power earth to my PC just because Nvidia can’t design a sound card properly.........
Maybe when somebody dies from electrocuting themselves and sues NVIDIA, maybe then they’ll listen.
How do content developers make audio for games with this racket going off is beyond me!

Hi GibsonRed
You mentioned you are using a power ground lift switch on your PC to reduce the hum. Can you tell me how this is done? I'm quite a newbie when it comes to electrics.
Many thanks!

Hi Dankeepsie,
My recommendation is to get an electrician to make you one.
That’s what I did. It is literally a normal plug socket with a big red oven power switch on the side that lifts the ground when I press it.
I can have a game screaming away with the noise, press the switch and it disappears entirely.
Just make sure you use a wireless pad! :D
Mines been running for years with no issues but just make sure you don’t go messing inside your pc with the ground lifted or you’re asking for trouble.

Thanks for your response. Are you recommending the wireless pad for safety reasons? :D
In many countries outside of the 'first world' it is quite common to have no ground on the plugs, and while I do agree that it does add an extra layer of safety, I believe they are actually not needed on a faultless circuit.

[quote="khmerninjai"]I have the same issue with my computer. Motherboard and/or GPU has a grounding issue and whenever it draws powers, it changes the pitch. It even picks up my mouse movements! I think the ground is going through my USB to my interface, then to my speakers. I eliminated this by using DI boxes with ground lifters as well as using a USB cable with ferrite chokes.

I've been spending about a month setting up my HTPC with MadVR and various surround sound headphone things. I spent an hour calibrating my 5.1.4 Atmos setup and sat down to watch things - I heard a weird noise. Not quite a hum but like a garbled noise. I tried to eliminate everything, rolling back windows updates. Then I saw your post. I unplugged all my USB cables - turned it it's the 10m extension cable I have that was causing it.
THANK YOU SO MUCH, that was driving me crazy.
