Hello, I am having problems with my sound card. In certain games, it seems to be making a cracking noise. I have an on board SigmaTec Audio card. I updated the drivers and it still does the crackling. I also tried to put in another older sound card but the computer couldn't read it and the driver wouldn't install unless the computer could read it. Is there anyway I could solve this crackling problem? Could someone double check and make sure I downloaded the correct sound driver if possible? My motherboard is an intel board, Intel D 975XBX I believe, not quite sure to tell you the truth if it is the XB or XBX. Thanks for reading and helping.
