I was cleaning up some softwares in my laptop, and i must have deleted something wrong, coz after restarting the laptop, the sound system went haywire, and my music/video files all sounded rather synthethized and the playback speed was faster than usual. Can anyone out here kindly advise me? Thanks! Btw, i'm new here and new to all these posting stuff. So my apologies if there's any procedure i missed out prior to posting this.
