I have a Creative Sound Blaster Live! 5.1 card in my computer which has konked out twice now. The first time my brother came over and fixed it (he's a wiz). And now the second time is this one. I have tried almost everything I could think of: unplugging and replugging in the card itself, uninstalling and reinstalling the drivers, checking the mute and volume settings. It might be the speakers, but the last time I had sound they worked fine but over time they began to crackle. Any ideas? I have no idea what might be wrong.
