Sorry, but I've forgotten and can't seem to figure it out by trial and error. My sblive has five jacks and i'm trying to differentiate the speaker jack from the line-out jack. I believe they are right next to each other on one end. As I recall the mike is the middle jack and line in is to the left of the mike jack as I stand in front of the computer. Anybody who has an sblive and can straighten me out on which is speaker and which is line-out, I would appreciate it. I'm getting lots of static when i try one of these jacks and it's hard to figure out what's wrong if i can't be sure which jack I'm working on. Thanks. Cheryl
