Sound problem: high pitched squeal and echo when volume is increased

[Kate_M]

product number = E0L69UA#ABA

I have just recently had a problem where when I turn up the volume (either through my headphones or the computer's speakers) I get a terrible screeching noise and feedback. I was playing around with WMM trying to get the narration to work, so maybe I mucked up something, but I reset the audio speaker and microphone in Control Panel > Sound, made sure the Audio driver was up to date and those haven't worked... Every time I turn up the volume past 20 I get a squealing noise with a low wavy subtone. Please help!
