May be that one user has muted the sound or turned down the volume to zero. That would be effective only for him. Get him too un-mute or turn the volume up..
My system has stopped working. I checked the device manager and there were no clashes with the sound devices. I observed that this issue only occurred in one of user accounts. If I logged in as administrator all the sound worked well. In the user account, when any sound was played a message appears saying no sound device installed. I have tried re-installing the AC97 audio drivers but nothing is happen.
