What this tells you is that you are not getting sound because your sound card is not properly installed or in a worst case is broken. That would be rare. Again, go to start, settings ,control panel, system, device manager tab. When you look in sound, video and game controllers in device manager what is listed? Is there a sound card listed? Is there an exclamation mark? If a sound card is listed (ie SBLive etc) highlight it and click on properties. Is the box exists in all hardware profiles checked? Click the resources tab. Does it say No clonflicts? What were the circumstances when the sound stopped working (ie new program installed, crash etc)? Video is relatively easy to troubleshoot compared to sound. There is little to the video in a computer: monitor, video card, video drivers. that's it. Sound in computers is essentially been jerry-rigged from the beginning and is a bit more difficult to pinpoint a problem. But we can keep working at it.
