Question GTX 980 Ti - Displayport for monitor, HDMI for audio output at the same time. Is it possible?

I'm looking forward to buy a soundbar for my PC which uses HDMI for audio input. I use a Gsync monitor connected with displayport to my pc. Because my motherboard doesn't have any proper audio output to 7.1 sound system can I use an unused HDMI port on my GTX 980 Ti to use as an audio output to the 7.1 soundbar?

Mind sharing the make and model of your motherboard(or the sound card you have on your system)? Have you narrowed down the soundbar you want to pair with your system? They will often have an optical input port which will allow you to add surround sound via one cable, though the soundbar needs to be able to deliver multi channel audio. in Sound Manager, you're going to have to select the default audio output device as your HDMI port that isn't connected to the display.
