This question already has an answer here:

Basically, no sound is coming out the television. I'm running out of idea of why?

Viewing the PulseAudio control panel, it's putting sound out the HDMI

The Television is not mute. I booted into Windows and the audio out the HDMI works fine.

    In case you use the open source radeon driver you may need to enable HDMI audio with a Grub setting: askubuntu.com/questions/67113/… – Takkat Feb 1 '14 at 18:52

    Glad you got it running :) +1 for the extremely well written question, but we probably have to close it as a dupe to the question I linked to. – Takkat Feb 1 '14 at 19:05
