Hi, I'm having problems with my mother's computer (Intel Celeron 1.0 GHz, Motherboard Asus P5GC-MX/1333). I know it is very old, but with it she can do all that she needs. Days ago, the computer stop to emit any sound. It has a Realtek sound card. When I plug the speakers in, the realtek sound manager shows as if it was connected to the microphone connector. What do you think is the problem? I apologise for my english. Thanks in advance.
