Another annoyance from microsoft but the good thing is it is solvable without needing to head to registry to tweak stuff (Which was their suggested solution -.-). First thing I noticed about playing sounds from wmp is the few seconds wait to start playing the songs. Something which did not happen when I played songs in xp.
If you listen to songs through your headphones or laptop speakers or you’re not an audiophile, the following will remove the few seconds wait.
1. Right click the speaker icon on your task bar.
2. Select playback devices.
3. Under the playback tab, double click speakers.
4. Under enhancements tab, click the disable all enhancements checkbox.
Play your music with satisfaction now.
