Today I took out a WiFi PCIE card from my PC. It was powered off when doing this and was very simple and I had no problems. Once I powered on my PC my headphones were making an odd sound, almost like a dirty old record sound effect. They are no longer being detected by my PC on both ports. (Front and back) I have verified that my headphones and the cord are working properly by testing on my monitors built in jack, and sound works fine. I already tried updating the drivers as well but with no success. I also checked if there were any apparent loose or unplugged wires. Only one I can see that is unplugged is a 4 pin plug that says "16W17" There are two of those on the bottom of my case that are unplugged. I really appropriate the help!
