Okay the situation is this I have been using windows XP sp2 for a long time now and all of the sudden there is a echo with my sound with everything from movies to games I would just like to know how to switch it off

Okay so no one knows how to fix this

I dunno if I am certain with this but do these 2 things.

First if you have any audio systems, like Realtek Audio, which is the one I have, check that and check the sound settings, it may be on a setting such as sewer pipe, which makes an echo.

Second, check if you sound card is functional, it may be broken in some may.

Hope I helped.

Thanks for the help
