I moved all my components from one case to a new one. As it was the first time in five years I removed all the components, I tried to carefully get the dust/tar/cat hair off, but I think I may have made a booboo anyway. The audio is completely gone, front and back. I removed the front connector from the motherboard but that didn't make the back connector work. So yeah, I think I must've done something wrong. I've been looking at soundcards but... would that solve the problem? If both the front and back connectors don't work, the problem would be on the motherboard itself, nein? If you think a soundcard could work; does anyone have any good experiences with free software drivers for a certain brand?
