I am an internet gamer, and that means I use a headset. I was playing Battlefield 1942, like any other day, and I went to disconnect my headset from the front port of my computer. I normally just rip the green thing out, like I have done hundreds of times, but this time it turned out different. The volume just stopped. When I try to play a song, it says 'No audio input found or there are problems with your sound device.' My speakers are plugged in and the green 'On' light is on. I use 'Creative' speakers and my sound card is an Realtek AC'97 Audigy. If you can help me out, that would be awesome.
