Hi Bushfiva,
To troubleshoot the problem, I would go through something like the following steps:
- Speaker problem - try plugging in some headphones into your PC directly and see if the same sound issue exists. If yes, then speakers are fine, if no, then speakers are the problem.
- Windows/Sound problem - Get your favourite (!) Britney Spears CD and put it in your PC CD drive. Play it in Windows Media Player and see if the sound does the same thing. If yes, then there is a Windows/Sound problem. If no, then play that same CD in iTunes instead, and see if the sound is good. If it's good, then the issue is with specific iTunes tracks, not Windows/iTunes itself.
- (most imporantly) Eject the Britney CD and crush it with a large block of concrete and berate yourself for purchasing such garbage.
That should at least get you heading in the right direction (well, a direction anyway).
