Setting up sharp 46

Trying to set up our new 46" sharp aquos and can't get audio. have the hdtv box from optimum. can you help?

Try to isolate the problem.

Try plugging in another source such as a DVD, is there audio? If yes, problem may be with the optimum box. If no, most likely a problem with the TV.

Also, if you are using HDMI with the HDTV box, make sure the box is set to output audio through HDMI.
