macOS Sierra 10.12 Audio Not Working (Windows PC)

[Max2002]

I know there are threads with the same problem but I tried many kext's and my sound isn't working.
In the Windows Device Manager (Windows 10) I have these devices:

Audio, Video und Gamecontroller:
- IDT High Definition Audio CODEC
- NVIDIA High Definition Audio
Audioeingänge und -ausgänge: (engl.: Audio Inputs and Outputs)
- Lautsprecher / Kopfhörer (IDT High Definition Audio CODEC)

I don't think that helps but here are the specs of my PC:
Intel Core i7-4770 @ 3.4 GHz
12 GB 1600 MHz DDR3 RAM
NVIDIA GeForce GT 640 4 GB
Old 160 GB SATA Hard Drive (connected over USB)

I hope someone can help me.
Thanks.
