Why wont my ipod nano 2nd generation work in my ipod dock?

I have an Altec Lansing ipod dock i just got for christmas for my ipod nano 2nd generation, It says on the box that it works for my ipod. But when i connect it to the dock it makes a noise that it has settled in and connected but the music just wont play!
Can someone help me?
I cant figure out how to make it work.
Thanks
