I am using a desktop computer with an Intel DP45SG motherboard with the built in sound card. Since recent times i am experiencing a problem with sounds. The problem is that im not getting a sound output from the line out port. I tried several headphones & speakers but it still did not work. So i tried using the front panel line out port. That does not work too. At time when i shake the jack of the line out cable i can hear a faint sound output. But that is also not constant. Therefore i tried re installing drivers, checking sound settings etc.. but i have been unable to fix it. Any suggestions?
