I've had this problem since windows vista, in windows xp i could record my line in perfectly, without any problems, but now, even if i enabled Stereo mix(tried mono also) it won't make any sound when i try playing some music. 
Anyony that can help me with this?
Also, as stated in the title, i'm using an USB sound card device.
