Where is the output of the JV1010 going.

Basic Trouble shooting would say put some earphones into the JV1010 and push the button in to hear the patch. And that thing has options make sure that the dial for Value (3rd on over) says GM and that the bottom led is on. You do that by pushing the knob in. Then set it at one and push the volume knob in and if you have earphones you should hear it go through a demo of the piano patch. Turn the Value knob to 17 and you hear an organ when pushing the volume knob in. Then try 25 and you hear a guitar.

Those are the same sounds as are going to come out the back.

On the back the slider should be set to Midi. You have 2 jacks on the back for left and right, mine then go to the mixer. I also run the keyboard to the mixer giving me two stero inputs into the mixer, this lets me run a beefed up sound when I want it. The mixer has output jacks and I take this to line in on the computer in the event I want to record audio. The computer audio can go either to adjacent line in jacks on the mixer OR to one of the channels on the mixer, depending on what you want to do with it.

The bottom line is if JV1010 is not hooked to computer and you use headphones you can ensure that it is working. IF you keep the headphones on and press the keyboard you should see a light flash every time and hear the sounds. Now fix where the sound is going because that is your problem.

And trust me I just did it with mine sitting beside me.
