I own a soundblaster live player 5.1 soundcard and a set of DTT2200 5.1 speakers, I was wondering if there is any way I can use the center speaker when listening to music files like MP3s even if they are not in .AC3 format. Currently I never really use my center speaker as I dont watch many DVDs on my comp and I dont no where to get .AC3 files from (even if I did they would b huge). A little help would be much apprietiated
