Hey guys, I am running windows 7 64 bit on my PC, where my headphones were working about a week ago. I have them plugged into the port on my motherboard, with an audio splitter where my speakers are plugged in. My speakers work fine, but my headphones have no audio output. I have gone into sound settings and set headphones as default device at 100% volume, it shows the green audio levels bar when music is playing, but no sound through the headphones. All drivers are up to date. All suggestions are welcome, Thanks!
