I recently installed a SSD and put a clean Windows 7 install. My headphones do not work in the back panel but do work in the front panel. Before I re installed windows 7 my headphones did work in the back panel. I have tried two different headsets and neither of them work now. My sound drivers are up to date and Device manager shows nothing wrong in the audio section. When sound is played the bars indicating "loundness" do show up but no sound is heard from them. I would have no problem using the front panel however my microphone jack on the front panel stopped working months ago. Help?
