I don't know whats wrong with my sound. The speakers power supply is on because the light is on. I tried the sound recorder but I can't tell if the microphone is really working because whenever I hit the microphone it doesn't make a distinguishable mark on the sound wave.But I can tell there is some activity in the sound recorder. I really think it might be the speakers because before when the volume is up loud enough I could tap the speakers and I could hear static but now nothing. Can anyone help?

I dont think it is the sound card because I installed new drivers. By the way I use ESS.
