I have XP home and a turtle beach sound card. Everything works fine except the line input. The line input works only if I plug in my cheap speakers in the green port which is the speaker out analog port. Line in doesn't work if I have my nice digital speakers plugged into the yellow digital out port. I am using line in because I want to convert my tapes to cd. Line in worked fine through my digital speakers on my sound blaster live card. I can figure out what is wrong and I did make sure that the line in box is unchecked in the sound box (meaning that it's not muted) Thanks in advance.

Do you have any Output Settings jumpers on your "turtle"? Something like for speaker output or digital output.
