No Audio/Sound on Alienware Hangar 18

Hi!

I've been troubleshooting my Alienware Hangar 18 for a long time now, that I can't get any audio from except headphone jack. I've tried with HDMI (see picture) and with Digital Fibre Optical Audio Toslink SPDIF but with no success.. What I can see is the driver installed correct. I've unistalled the sound driver but still no sound.

I've tried with different settings on both TV and computer.  Is there anyone that know what the problem could be?
