1) make sure under volume controls the line-in is not muted, and has some volume.
2) make sure you've not set your system up to use Line-in as 'Rear speakers' or something. Can't remember if the NF7-S has dedicated jacks for these. Some boards only have 3 jacks - line out, mic, and line-in, and you have to use the software (or jumpers) that comes with the board to switch the mic/line-in between their defaults and rear-left/rear-right and centre/sub. If you have 5 analogue jacks on the back of the PC then this probably <i>isn't</i> your problem.
3)make sure you've got all the drivers installed properly. (although since you have the nforce applet, sounds like you have done this)
4)Why are you trying to connect a CD player to a PC anyway? Just rip the tracks into MP3 to save yourself the hassle in future! Get with the program, man.. :wink:
