For those of you that have Windows Vista....I just fixed something that has been bugging me since I bought my new Dell PC a few months ago....
When you play an audio file (MP3, WMA, WAV) through a link on the web or maybe an email....there is a 5-10 second delay in the file playing.
To fix this do the following:
Go to the Control Panel and open the Sound properties:
Click the box that says: "Disable all Enhancements"
Press OK twice and.....there you go...no more delay in Media player.
(this should work for Vista...not sure if there is an issue in XP)
