An audio driver for Windows 10 (only tested on x64) that works as a virtual audio cable. Adds a virtual speaker that routes all played audio into a virtual microphone device.

For development I mostly used a virtual machine to see if the driver worked or crashed and to debug the code.
Here's the basic installation process I used to install the driver during development (basically just devcon):
