Same problem for me.
Just received my new AW988 headset and not possible to configure or see the audio section in AWCC.
Area 51 R5
After updating to the newest version of command center the entire audio section is missing, no audio profiles, no mixer, nothing. This also means that my AW988 headset cant cycle through audio profiles, the button is useless. I have tried updating audio drivers, updating Nvidia Drivers, it just seems to be missing.
