I would like to use the Headphone output of my Laptop and connect it to my amplifier. I know I need a mini to RCA cord. However, when I tried it, the volume was much lower than the other components in my system, such as my DVD player. Any recommendations on how to increase the volume of the laptop (already at full level) to the same level as the DVD player? I'm on tight budget to, so the cheaper the recommendation the better.
