Whenever I try to play a disk that has audio on it (CD's) the speakers make this crackling noise while playing it. It does not do this when I try to play audio files that are already on my computer , it only does it when I'm using a cd. Yet, if I rip the same cd that is making the noises onto my labtop and play the music from the labtop it plays fine without any noises. Could it still be the lazer in the computer if it copies the disk onto the hard drive with out the noises on it?
