Hey so I have a Dell Inspiron 15R-5521 (i believe is the model) with windows 7 and I just wiped everything and reinstalled windows 7.  Everything is working pretty well other than when I plug in an auxiliary cord it doesnt play through the speakers, just keeps playing through laptop speakers and I dont have the MaxxAudio program that the computer came with anymore which made the audio much better quality too.  So is there anyway to get that program back and get my speakers working? 

Thanks
