Starting with the basics:
1 - Are you sure the device is showing normally in the device manager ?
2 - Did you selected it as the default device in the sound reproduction ?
3 - What is the version of the driver in the device manager ?
4 - Youre using wasapi, ASIO or directsound ?
I will post some screenshots for this.
I am using ASIO
So I don't understand why it doesn't work
