Can someone PLEASE help me? I have a brand new acer, Aspire 3002LC laptop with AVG fully installed. I went to play a dvd & could'nt get any sound. My computer is telling me 'code 10' & no 'audio device'. I have tryed system restore twice but to no avail. Media player 10 was updated & it happened directly after that. Is there a chance the program was'nt fully installed? How would I fix that? Also my volume control on the bottom right-hand corner of my computer has dissapeared. Could somebody please attempt to explain how to fix this probelm in very simple terms. I am not great with computers. Much appreciated x
