Problem about USART VMUSIC2

sorry if I post in a wrong forum.

I was use a code in
http://www.arduino.cc/playground/Main/VMUSIC
arduino playground with vmusic2 simple source code
with my jx-mega128
to control a vmusic2 module
I was connected RX on VMUSIC to TX on board / also with TX
/+5v ,Ground, CTS#cto ground

and the result was turn out like this
-the led in VMUSIC2 blinking / my flash drive blinking in an any play command and stop blinking in any stop command(does this mean that the firmware and the code work out?)
-but the music doesn't turn out to my head phone.

  • I just test with V3A/VPF xxx.mp3 but it still doesn't work

and the question is what wrong with it?

maybe you will double check the code before you accept your mistake like me I just accept a mistake if my problems did not fix any more I have many mistake in my life I doing.
