The sound you hear is probably emi. You can buy some cheap ferrite beads for the 6/8 pin pcie cables which should help a bit, if you think it's coming from the gpu.

You can try moving the power cable used for the speakers to a different plug in the room as well.

Yeah it's a really odd problem I've never experienced before. It changes with the tone of the gpu and when it's under load in a game it comes through the speakers, even moving my mouse changes it, it also sometimes chirps as well. All hardware is the same apart from motherboard and cpu, how does changing a mobo affect this sort of thing. This is my 5th motherboard and pc I've built and first time I've come accross it. Same power supply, same gpu, same speakers etc. The power supply and speakers are on different wall sockets to try eliminate this but hasn't helped. What are ferrite beads, never heard of them before and where would i get them? I'm located in Australia. I think the sound is coming from the gpu as it's consistent when it's under heavy load but weird I've noticed moving the mouse and typing on my keyboard affects it as well.

You can google ferrite beads, they are pisces of ferrite that fit around cables to create an impedence to prevent EMI from leaking out from a power source (the very short of it).

Mouse movements alone will cause the VRMs on the motherboard to active/deactivate because of the load requested by the CPU. If you haven't changed any VRM settings in bios, by default, this is how they will behave. This in and of itself can cause EMI and create the interference you are experiencing. There is also a setting called 'spread spectrum' for VRMs that should be enabled by default as well. This will reduce EMI emissions by varying the switching frequency of the VRM itself.

Mouse movements will also cause the GPU VRMs to change their state as well.

The isn't all that much you can do besides isolating the speakers as best you can from the EMI source. The ferrite beads my help but it's not likely to resolve the issue completely.

I'll have a look for those ferrite pieces. Cpu is overclocked. Spread spectrum, I'll dig through the bios to see if I can find it. I'm still getting my head around Evgas bios (first time Evga and Ryzen user). Didn't know the mouse can be a culprit too that's handy to know cheers.

I'll move my speakers and amp further away from the mobo if I can. It's currently set up with the test bench stand it came with until I get the rest of the watercooling gear to put it in it's case so also wondering maybe as the i/o isn't touching a case that's possibly doing it too. I'm still learning alot about the ins and outs of pc's etc

Can you test using headphone out of the amp? Wouldn't be surprised if they work better. Some speakers just have super sensitive inputs (usually rca Jack's especially) and the auto cable acts like an antenna, just grabbing tons of interference is it's around.

Is the noise connected to frame rate or some other source e.g. moving the mouse?
 
I wonder what EVGA set the default setting for spread spectrum.  I don't recall seeing it on the BIOS settings.
 
I've heard of using different cables or ports for power, display etc have helped some folks.

No idea just depends how under load my titan rtx is under in different games and could be related to the frame rate but unsure but mouse does effect it with speakers only not headphones

I've never seen the setting in the bios of my X570 Dark, wonder if it's under cpu configuration or something perhaps

I do have a new stereo rca to 3.5mm cable on the way. I have two separate power boards and have been switching plugs around to see if anything helps but no luck yet. I've got psu separated from the rest of the stuff. Psu is an Evga Supernova 1600 P2, i have a 1000 G5 and 2000G+ on hand as well

Is your screen, PC, and audio gear on the same power strip?  If not, try doing so.  Might fix a ground loop of sorts by having connected equipment share the same/common ground. Next would try another mouse or USB port, then after would be to isolate source eg unplugging the screen video cable, check for noise, unplug sub, check for noise etc.  
 
After that it's probably addressing VRM speeds or messing with BLCK.  

What’s your setup and other peripherals?
 
 

So it's definitely linked to frame rate as it drastically changes with it. Also left side is louder than the right side despite volume for both sides is identical so this shouldn't be an issue. Definitely something wrong with the audio because of these issues. Yet it's only speakers effected not headphones but i know my audio equipment is fine because it works on my other motherboard no problem. Honestly it's not worth rma but still this shouldn't even be happening. Will try a pci sound card to see if it works properly that way with zero issues. Pretty diasapointing for over $1100 for a high end motherboard to be honest but will see how the sound card goes in a months time when I get it, shouldn't have to spend more and go this route but have no choice since I've tried everything else to no avail, other than this it's a great board despite other minor issues not worth mentioning as they're more of an inconvenience than anything else

TBF, I wouldn't consider any on board audio to be worth much in terms of quality or isolation. You could honestly buy even a decade old used sound card and get much better quality out of it (a creative x-fi titanium hd comes to mind).

Though, tbh, if it is only the speakers where the sound is an issue, I wouldn't be putting it on the motherboard.

My setup is exactly the same as it was before with my old motherboard and never had this issue so i do lean to the motherboard
