No Audio sound when using HDMI cable

Hi, I have a Dell Inspiron 15, 5000 series, and recently I tried using the HDMI cable to my TV, however there is no audio from the TV, the only audio I get are from the laptop speakers.

I have tried searching for a solution and I think I am missing some extra drivers(or software), as the Sound, playback option I do not have HDMI audio option?

I have also unhide unregistered auto drivers etc, there is nothing extra listed, just the laptop speaker playback option.
