sound - Ubuntu doesn't play audio through HDMI

I have an Asus x55l laptop. I hooked up my laptop to my TV and the video works fine. However the audio is played through my laptop. I tried changing the audio settings to play through HDMI, but upon testing there was no sound. I tried changing configuration on pulseaudio and still no sound.

Here is my aplay -l output:
