Noob question about 3520

I got my 3520 today, installed no problem. Now I’m new to this so please bear with me. I have a dell 8200 with 2 bays. I took out my cd burner and put the nec in its place. I set the jumper the same as my cd burner. Not master, not slave, cs? Now when I play a dvd there’s no sound. If I put an audio cd in the drive it works fine. Any ideas? Thanks in advance. Jeff
