I have an old Sound Blaster Live in my Dell Dimension running Linux Fedora. I need to use line-in and line-out. I have the line-in working fine but can't get the line-out going. Two questions: 1. In Fedora amixer, what is the control to adjust line-out volume and is there an additional control to activate it? 2. The SB has 5 jacks on the rear. can anyone identify which one is line-out?Left to right (from the rear) they are: DB9 connector Unknown Speaker-Out Microphone Line-in Unknown Thanks for any help. Jim
