I recently had all my stuff transferred to a new case and installed a new power supply and graphics card. Everything is going well except I can't hear anything at all. I don't have speakers I use headphones and I have plugged them into every audio jack and still nothing. Windows says "You just plugged a device into the audio jack" when i plug it in, and i can see that there is sound being played, but I still hear nothing. I already checked if it was muted etc and I have tried 2 different headphones. I am using windows vista if that helps.
