samrai shadown 4 sound problem

I tried today my samurai shadown 4 mvs cartdigde and sound was gone. It has worked very well before and i tried to clean it too. I have a 4 slot machine and i tried slot 3 with different games; no problems. Any idea where is my sound ?????

Does the cart always worked great?

You should post this on the tech forum.

It would help you more, but it may be a rom problem. <img src="graemlins/spock.gif" border="0" alt="[Spock]" />
