You will need to configure the HDMI output in your sound preferences, left click the Cog in the top right corner then select System Settings then select the Sound option.

You will need to select your HDMI output on the Hardware tab,

Sound options - hardware

And Output tabs

Then close the dialog box and it should be working. I have to do this each time I use the HDMI output on my laptop - you will need to change back to the internal audio output if you use speakers from the audio out plug.
