Samsung NC10 Sound Problem

I have a Samsung NC10 netbook and it is brilliant. The sound however has driven me mad. The speakers are tinny but worst of all the sound was horribly distorted even with earphones. After much fiddling I eventually found the solution. I opened the Realtek Sound Effect Manager in Control Panel. Under the Sound Effect tab there is a Karaoke icon, make sure that there is no X showing in the circle. If there is click to turn off. Make sure all the equalizer sliders are on Max and the environment is set to or Padded Cell. Success sound back to normal!
