Yesterday, I installed a new PSU, everything is working fine, except the headphone jack and USB microphone. When I plug the headphones into the jack, the computer registers that they are in, but no sound comes from the headphones, it comes from the speakers, I have tried to set the headphones as the default, still nothing. A similar thing is happening with my USB webcam/microphone. The webcam works fine, but the microphone doesn't. Same as with the headphones, the microphone is recognized as being plugged in, but none of my friends can hear me when I try to talk to them. I have tried to update drivers to see if that is the problem, but they are all up to date. Any help with this issue would be greatly appreciated. Thank you.
