Nikon D7000 HDMI Playback No Audio sound

I bought the recommended HDMI cable for Nikon D7000. I see great video playback on my HDTV but there are no Audio. I played the file back on my computer= Sound YES. I played back on the Camera and = Sound Yes.

I even tried my pocket video camera (same connector ) = Sound Yes and Video.

I used the supplied A/V cable and play it on AV channel. Sound Yes. But I don't want to play in this mode because of picture quality

I'm hoping if you have Nikon D7000 and try this setup let me know soon.

According to page 192 of your manual, it should work. Before you start the return and repair process with Nikon, turn the volume all the way up on your TV.
