Dropped Zune. Screen cracked and left side speaker does not work.

I dropped my Zune on the ground and the screen cracked. It still worked fine for a while, but then the sound stopped coming out on the left side. This happens anytime I plug something into the headphone jack whether it be headphones, a speaker, or my car. Music plays perfectly fine when plugged in from the bottom on something such as a charging station. Screen is still cracked but still works anyways. Is there any way to repair it or should I buy a new one? If there is some way to repair it, tell me how to do so and how much that would cost.
