why is there no sound???? hey, a few days ago, while listening to some music, the sound just stopped. at first i thought it was just the song, so i tried to play other ones, but i still couldn't here anything. then i thought it must have been my speakers, however i turned on other applications that used sound and they worked perfectly. so it must be the media player. i've tried re-installing it and going through all the options to c if theres anything i can change, but i can't find anything. can u guys plz help me!!
