In which emulator have you tried ? Have you tried in a real device?

I guess your wav file is bigger than your emulator's or real phone's heap-memory size (a long-time "feature" on Nokia phones). Try a wav file less than 1 Mb in size, and if it will not working, check out the file path. If you'll get the same errors, try to find a simple player code from the net.
