If your cable box has settings for the sound output, check to make sure the sound is selected to be output through the HDMI. If that doesn't help, then power down everything (unplug or turn off power strip) and power back up. That second step fixed my blueray player sound output. Before I bought this TV, I was outputting sound from the blueray directly to a home theater amplifier using the coaxial digital audio output. I disconnected the coax digital and connected the HDMI to the TV. But I powered the blueray up before the TV. Powering everything back down and re-booting allowed the blueray to "find" the TV audio through the HDMI connection.
