constant buzzing in headphones

[Cygi]

Hello everyone, A week ago I bought a new rig with a new mobo, Gigabyte Z390 Gaming X. Since then Ive been hearing buzzing that is very quiet but noticeable and annoying af. My outlet is not grounded but I didnt experience anything like this with my previous pc. Now the interesting part, the buzzing changes pitch and intensity depending on what Im doing. Everytime I launch a program it stops for a second or two, running stress test makes it silent. I have to mention that after turning on my pc the buzzing starts exactly when the logging to your account appears. Im sure its not my headphones I tried it with different ones. Will a sound card or a UPS help? Thank you all for answers

Could be because it's not properly grounded. Does it happen on other devices, or with other headphones/speakers?

I doesnt happen with any other device, as I said I dont have grounded outlets in my room. I tried different headphones

By any other device what do you mean? Can you only replicate the issue with those headphones on your PC?

 

 

Are you using an external DAC/AMP or headphone splitter or anything?

My old pc I used to use, I can replicate with every headphones I have, I dont use a DAC nor a AMP

Yeah, probably bad grounding or something. I feel like a decent DAC would have "built-in" grounding...how do none of your outlets have grounding?

well only outlets in my room doesnt have grounding, it confuses me too. Are you sure a DAC will help? What about a sound card?

You can try a soundcard, idk. If you're investing in nice audio stuff I would get an external DAC/AMP.

Get an electrician and do the wireing.

I dont think its possible...

I know nothing anout those, also Im on a pretty tight budget like 60$. Can you recommend me something?

It's possible. I had no grounding in my room, took the electrician a few hours to add a cable.

but Im not sure if its becouse of the lack of grounding...

May sound odd, but be sure the jack is snapped in all the way, and check for clearance issues that may be preventing the plug from seating fully. There's a lot of tolerance issues possible with 3.5mm jacks and plugs, and if the tip is not fully seated, you can get ground loop issues.

 

The variance in sound that relates to load suggests that the fans are creating the most of the RF noise being inducted, if not via the ground load, then directly out from the fan or headers. Again, be sure they're all plugged in fully, and that they are spinning freely. If fan wires are anywhere near the header for the 3.5mm plug, move them away. Same is true even for the sound processing chip (whichever one is handling it) itself, so if it is integrated into your video card, be sure the wires are routed away from that, too.

Take a multimeter and measure yourself.

Do not use a PC on a socket without grounding.

it is snapped all the way, I also have a headphone jack on top of my case, the buzzing there is doubled. I dont think its because of the fans, the pitch changes exactly when I launch a programm and you cant call chrome a load.Though  I ll try to reroute the cables

Dont have one

UPDATE

I found a sollution. I have this wheel on the cord of my headphones that I can adjust volume with. It is not causing the problem but if i turn the volume down on it and turn it up on windows the buzzing is completly gone. Neither the less thank you all for your time

Aha! Mismatched gain is not good, because it will amplify very extremely modest noises like that. In general, you shouldn't amplify an already amplified signal. If the headphones use batteries, you should use (or possibly set the jack to) a line level output, so you can use the headphone volume control. If that isn't an option, Set Windows volume to half, then test the volume range on the headphones. If the hum or other distortions start to happen in the top quarter of the headphone volume range, adjust the Windows volume to 25% and try again. Once you can cleanly use the full headphone volume control range, leave the Windows volume there. Even if the headphones do not use their own power, this is a good method.

I already RMAed like 2 things in the past month, I have the worst luck ever. It works so I’m fine

But I used many other headphones without an AMP, same results
