There a few options you can check:
first of all, try to hook an audio cable to the TV. Some laptops do not support hdmi as audio output.
also, I would try to check if your hdmi audio device is set in your audio controls. Appaarently, in most cases the laptop speakers are playing by default, which means you will have to set the hdmi audio yourself. Right click on the volume control icon in your desktop (minimized icons, to your right), then go to playback devices (depends on your windows of course), then check if the hdmi is active or not.
