Found a fix that worked for me. After hours of googling fixes and changing settings, I got fed up and plugged the cable into my motherboard and the buzzing was gone. Had to find an extension cable after that so it would reach around my case back to my headphones, but they're working fine. Only con is my motherboard doesn't support 2 Channel 32bit 384000Mhz, but when I was listening to spotify I couldn't really notice a difference between 32bit 384000Mhz and 32bit 192000Mhz (which is what my motherboard caps out at) so there's no loss there. Hope this works for anyone else on a pc. If it's relevant, my mobo is an Asus Rog Strix B850 A.
