which drivers are you using? just to clear things up as it does make a difference. have you been into the windows sound set up in control panel? you get a choice of recording devices. its a long shot but if your line in is not set to the soundblaster maybe your pc is reverting to onboard motherboard sound

i don't think you need an interface - you should be able to get the current set up working
