I've had this problem since yesterday. I logged in and there was no audio. Did the basic troubleshooting already to no avail. Sounds work on my other games.

• Checked game sound settings
• Checked computer sound settings
• Restarted FF14 Client
• Restarted PC
• Updated Drivers
• Turned DX11 on/off
• Changed window size (apparently some people fixed this issue using this method)
• Changed speakers/headset

Specs:
OS: Windows 7 Ultimate
Processor: i7 6700k (I'm not overclocked BTW)
GFX" GTX 970
RAM: 16GB
Board: MSI Z170A Gaming M5

I wish I could resolve this ASAP. I always sleep with FF14 logged in with Night in the Brume playing in Orchestrion... (silly, I know)
