Sound via DisplayPort?

[mahius]

So a good few weeks ago, I was fiddling around with my sound, since I have to manually switch between headphones and speakers by plugging the cable into the back (HP cable to the front of the case isn't possible due to cable management). I saw that in playback devices, my Monitor was listed under Nvidia High-Definition Audio.

Fast forward and the other day I found out that DisplayPort can apparently carry sound? So do I not need to plug in the audio cable into my monitor to use the built-in speakers? Of course, I have a few HDMI ports spare on the HDMI splitter if I can get sound through that like with most modern HDMI devices. But I'd have to buy a new cable and I'd rather use what I already have if possible.

Here's the important bits of my setup (even though some of it is in the sig). Monitor is the Asus VE278Q, GPU is GTX970, Motherboard is Gigabtye Z97X Gaming 7. The monitor is currently connected to the GPU via Displayport and when the headphones aren't plugged in, the monitor also has a regular 3.5mm audio cable connecting it to the sound on the motherboard. Can I really get sound via DisplayPort or even HDMI? Is it ridiculously simple and I just don't know? Or have I been fed lies?

I appreciate the feedback, whether it can be done or can't, at least I learn something from it.

Cheers for the replies. Turns out the sound settings on my monitor change depending on the input used. On DisplayPort, the options are line-in and DisplayPort. Normally on VGA/DVI, there's only the line-in option. Of course, I switched it to DP and set the monitor as the default device in Playback devices. Sweet! I love DP even more now, HDMI has nothing on it!

I must ask now, is there any downside to getting sound through a graphics card rather than the motherboard audio? Will I notice any loss in quality? Also, would this work with a multi-monitor set-up? I.e. can I pump out sound through multiple monitors connected via DP/HDMI? Sounds silly, but I'd just like to know what's possible.

And to think I was manually changing audio cables for more than 6 months... XD I sure do love being enlightened on stuff like this.
