DisplayPort (or HDMI) audio #AUDIO

Hello everyone (not sure if this or Graphics is the correct section),



I have the following monitor that comes with integrated speakers, but they work only with DisplayPort or HDMI since there is no audio input jack (oh my god why?!).

So my question is, how can I use DisplayPort/HDMI to transfer also audio signals?

I'm a noob but I can always learn. :P



Here are my specs:



- Mountain Lion 10.8.3

- i7 3770, Gigabyte Z77X-UD5H

- 4x8GB Corsair Vengeance 1600 MHz

- GeForce GTX 660 OC

- Samsung 840 250GB SSD

- 2*WD Black 4TB in RAID1.



Thanks in advance!
