I was having a problem with sound on Madden 2005. I was getting no sound. None. I changed sound cards and then I get mp3's playing and game sounds but now my video has 3 or 4 images and is jumping all over the screen, when I exit it locks up. The only other thing I did was updated my video drivers because I was unsure before if it was a video or sound giving me the problem. Should I and can I go back to old video drivers and If I can I am not sure which driver I had. Please help
