I have the same issue, but for me when I uninstall CUE, there's still no sound...
I got headphones like 2 months ago, they work great in the beginning. Then around 3 weeks ago I reinstalled system to Windows 7. They worked only if I didn't installed CUE. After 1,5 week I installed it just to check and it worked, could've changed setup and lights. Now, 2 days ago I had to reinstall system again. Of course headphones worked only without CUE, but today even tho I didn't installed it, there's no sound. System is finding headphones, there's sound in my settings, but nothing comes from the headphones. There's even that smal green line going up and down in sound settings that means the sound is coming from somewhere, but not going throu my headphones. I don't know what to do. If someone finds solution, please reply.
