Audio Input on Realtek HD Audio Problem

[RichVisuals]

I'm unable to select any audio input devices.
Direct Sound options are greyed out, and the primary windows device (Microphone Realtek HD Audio) when selected does nothing and the Audio Input Box remains on None.
Any ideas?

Av6 beta 3
I've confirmed the device is working normally in windows 10

Update : Fixed, device sampling rates must match the sample rate in R6

But still cannot get R6 to listen to the microphone input
