or just selected web sites or online radio stations?
What player is being used for this online audio, Flash, WMP, or some other? Example, I'm listening to an online radio station and playback is using the Flash plugin.
Have you tried a different browser?

My Compaq RS4000 laptop with Windows XP Pro has developed a problem with streaming playback of online audio. It has a ringing echo that is very annoying.
It plays downloaded, stored and network audio files with no issues. I tried to do a restore but the earliest dates available apparently are after it happened and don't fix it.
