I am having problems with a set of computer speakers. They make a crackling sound when the volume is turned up. I don't seem to notice the noise when the speakers are turned way down. The volume setting in the computer are set at half and I have tried another set of speakers and they too make the same noise. The computer is a 2 year old HP using windows xp as the operating system.

Any help or insight anyone one might have on this would be greatly appreciated. Thank you

You'll get that when the audio driver is corrupted or if another device is on the same IRQ.

ah good to know , got the same thing with my system, but only the rear 3 speakers make strainge noise, rest is normal.
