Question Buzzing / humming backround noise when playing games, screeching in headphones when moving mouse, not from hardware ?

Hi!

i would have put this in Audio if there was one but i guess this will have to be good enough

i recently went all out shopping spree got basically all new PC first monitor LG 27GN850-B and mobo Asus strix 590 F gaming + cpu 11600K

i noticed some audio dropouts coming from my SPDIF only dac and i read that the 590 is infamous for audio dropouts got a replacement and was still there so i went and bought a USB DAC for 250 ish USD to circumvent the SPDIF while i was waiting on the dac i grabbed a 3060 v2 12gb ram and now with the dac there is a lot of background noise which gets louder when i play games i read it could be coil whine and recommended to limit FPS this helped ever so slightly.

i then read it could be due to a bad PSU and sure the one i was using was 12 ish years old so i got a new one didnt help
i also read that it could be electrical interference due to unshielded cable so i went out and bought an Audioquest USB A - C Carbon for250 ish USD did not help the background noise much but i do have better audio quality...

i also read that it could be a ground loop issue and recommendation was to put all devices on the same wall socket which i already were doing so it cant / shouldn't be that

i have checked windows audio settings (dont have motherboard drivers installed) and enhancements are disabled some ppl say mute mic and line and can not see any of that probbaly due to no motherboard audio drivers

Dac drivers are installed and up to date

i have ordered a 3 meter Displayport cable from Supra that is tripple shielded for 70 ish USD no idea what it will arrive

i also read that some old / cheap peripherals can cause this and recommendation was to unplugg them one by one til the sound is gone i did that and nothing changed

so far my only guess is that the motherboard it self have bad USB ports and will probbaly go and buy MATRIX ELEMENT H USB 3.0 Controller

another thing i been thinking of to try is this but i dont want to cough up 500 USD for something that might not work

Just one of those problems where you need to keep trying to narrow things down by swapping, eliminations, etc..

(No harm in having the wall socket(s) checked. Just as a matter of general safety....)

And it does appear that you are narrowing it down.

Just remain open minded and continue to be methodical. Change only one thing at a time.

The real "Eureka" moment is when you discover how to make the noise start and stop at will.
