ADAU1452 exposed pad not connected symptoms

I have a question regarding the exposed pad on the ADAU1452. I have assembled five boards with this part, and the DSP is apparently not running - it isn't even getting warm with power connected. I suspect the exposed pad has not made contact to the ground pad below it on the PCB. If the exposed pad is not connected , will the part not work at all as in this case  ?
