I just started playing again after 2 years off. Before, I had my audio output with an optical cable and got 5.1 audio with DD Live.

Since then, I've moved to audio through my GTX 770 over HDMI. I have my audio set up correctly in Windows and I can test each channel. My receiver shows my computer is outputting 5.1 Other games have no issues with surround. But, in FFXIV, I don't get anything out of my center or side channels.

There are no settings in the game. What should I be doing to fix this issue?
