Hey all, I'm having some really bad interference in my headphones as of late. I've tried multiples pairs on my PC and it just has a horrible whining noise in them. It's not the headphones problem either, they work perfectly on my laptop/phone. I also have tried an external soundcard, just to see if my onboard was the problem, I get the same interference. I've made sure all my drivers were updated, every windows update, etc and I still have the problem. I've unplugged all other things on the PC and I still get the interference noise. What should I do?
